Holographic data storage is a potential technology in the area of high-capacity data storage currently dominated by magnetic and conventional optical data storage. Magnetic and optical data storage devices rely on individual bits being stored as distinct magnetic or optical changes on the surface of the recording medium. Holographic data storage records information throughout the volume of the medium and is capable of recording multiple images in the same area utilizing light at different angles.
E-paper is a revolutionary material that can be used to make next generation electronic displays. It is portable reusable storage and display medium that look like paper but can be repeatedly written one thousands of times. These displays make the beginning of a new area for battery power information applications such as cell phones, pagers, watches and hand-held computers etc.
Like traditional paper, E-paper must be lightweight, flexible, glare free and low cost. Research found that in just few years this technology could replace paper in many situations and leading us ink a truly paperless world.

Silicon Photonics: A Solution for Ultra High Speed Data TransferIDES Editor
Silicon photonics is the integration of integrated
optics and photonics IC technologies in silicon. Silicon
photonics has recently attracted a great deal of attention since
it offers an opportunity for low cost solutions for various
applications ranging from telecommunications to chip-chip
inter connects. Two keys to this advancement are the increased
speed of communications (now at the speed of light) and the
increased amount of data that can be transmitted at once (i.e.,
bandwidth). Silicon photonics is the study and application of
photonic systems which use silicon as an optical medium.
The silicon is usually patterned with sub-micrometer
precision, into microphotonic components. These operate in
the infrared, most commonly at the 1.55 micrometer
wavelength used by most fiber optic telecommunication
systems. The silicon typically lies on top of a layer of silica in
what (by analogy with a similar construction in
microelectronics) is known as silicon on insulator (SOI). Today
the problems associated with multi-core processors with copper
interconnect are Latency, Bandwidth, Power dissipation,
Electromagnetic interference and Signal integrity. Micro
processor designers use the integration of number of
transistors that could be squeezed onto each chip to boost
computational horsepower. That in turn caused the amount
of waste heat that had to be dissipated from each square
millimeter of silicon to go up. One problem we are facing in
this effort is that micro processors with large numbers of cores
are not yet being manufactured. Fiber optics has a reputation
as an expensive solution because of high cost of hardware and
Fabrication is done using exotic materials which are costly.
The methods used in assembly and package of these
components are also expensive. A recent break through in
silicon photonics is in the development of a laser modulator
that encodes optical data at 40 billion bits per second. Finally
reached the goal of data transmission at 40 Gbps speed,
matching the fastest devices deployed today with least cost of
processing and showing the ultimate solutions to the problems
associated with copper interconnects in multi-core processors
and expensive fiber optics.
In this slidecast, Brian Welch from Luxtera presents: Silicon Photonics for HPC Interconnects. Luxtera is the first company to overcome the complex technical obstacles involved with integrating high performance optics directly with silicon electronics on a mainstream CMOS chip, bringing direct “fiber to the chip” connectivity to market.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
4. An optical computer (also
called a photonic computer) is
a device that uses the
PHOTONS in visible light or
infrared ( IR ) beams,rather
than electric current, to
perform digital computations.
5. Introduction
• Growth of computing technology increased the need of
high performance computers (HPC) significantly .
• The choice is motivated by several features that light
has:
• • Actually the fastest thing that we know, and
speed is exactly what we need for our computers.
• It can be easily manipulated (divided, transported,
• delayed,split etc.)
• It is very well suited for parallelization.
6. Optical computing technology is, in general,
developing in two directions.
Electro optical hybrids: One approach is to
build computers that have the same
architecture as present day computers but
using optics.
Optical mode: Another approach is to generate
a completely new kind of computer, which can
perform all functional operations in optical
mode.
7. Why we Use Optics for Computing?
• VLSI Technology: To make computers faster, their
components must be smaller and there by decrease the
distance between them.
• But they are limited not only by the speed of electrons in
matter but also by the increasing density of
interconnections necessary to link the electronic gates on
microchips.
• Einstein’s principle: One of the theoretical limits on how
fast a computer can function is given by Einstein’s
principle that signal cannot propagate faster than speed
of light.
• The optical computing comes as a solution of
miniaturization problem.
8. Features of optical computing
• Optical interconnections and optical integrated
circuits have several advantages over their
electronic counterparts(short circuit).
• Optical data processing can perform several
operations in parallel much faster and easier than
electrons.
• They are compact , faster and light in weight.
• Optics has a higher bandwidth capacity over
electronics, which enables more information to be
carried
9. OPTICAL COMPUTER
An optical computer, besides being much faster than
an electronic one, might also be smaller.
Bright flashes of laser light can be sent hundreds of
miles along fine strands of specially made glass or
plastic called OPTICAL FIBERS.
Instead of transistors, such a computer will have
TRANSPHASORS
These are switches that are activated by beams of
light rather than by pulses of electricity.
Unlike transistors, transphasors can be built to handle
several incoming signals at once.
10. Beams of light can crisscross and
overlap without becoming mixed up,
whereas crossed electric currents
would get hopelessly confused.
Also, the arrangement of connections
and switches would not have to be flat,
as in an electronic computer. It could
be placed in any direction in space,
allowing totally new designs in
information processing
14. SOME KEY OPTICAL COMPONENTS FOR
COMPUTING
The major components are:
1. VCSEL (VERTICAL CAVITY SURFACE EMITTING LASER)
VCSEL (pronounced ‘vixel’) is a semiconductor vertical cavity surface
that emits light in a cylindrical beam vertically from the surface of a
fabricated wafer.
But rather than reflective ends, in a VCSEL there are several layers of
partially reflective mirrors above and below the active layer. Layers of
semiconductors with differing compositions create these mirrors, and
each mirror reflects a narrow range of wavelengths back in to the
cavity in order to cause light emission at just one wavelength.
16. 2. SMART PIXEL TECHNOLOGY
• Smart pixel technology is a relatively new
approach to integrating electronic circuitry
and optoelectronic devices in a common
framework.
• Here, the electronic circuitry provides
complex functionality and programmability.
• While the optoelectronic devices provide
high-speed switching and compatibility with
existing optical media.
17. 3. WDM (WAVELENGTH DIVISION MULTIPLEXING)
• Wavelength division multiplexing is a method of sending
many different wavelengths down the same optical fiber.
Using this technology, modern networks in which individual
lasers can transmit at 10 gigabits per second through the
same fiber at the same time.
• WDM can transmit up to 32 wavelengths through a single
fiber, but cannot meet the bandwidth requirements of the
present day communication systems. So nowadays DWDM
(Dense wavelength division multiplexing) is used. This can
transmit up to 1000 wavelengths through a single fiber.
That is by using this we can improve the bandwidth
efficiency.
18. 4. ADVANCES IN PHOTONIC SWITCHES
Logic gates are the building blocks of any digital
system. An optical logic gate is a switch that
controls one light beam by another; it is ON when
the device transmits light and it is OFF when it
blocks the light.
19. MERITS
• Optical computing is at least 1000 to 100000 times faster
than today’s silicon machines.
• Optical storage will provide an extremely optimized way
to store data, with space requirements far lesser than
today’s silicon chips.
• Super fast searches through databases.
• No short circuits, light beam can cross each other
without interfering with each other’s data.
• Higher performance
• Higher parallelism
• Less heat is released
• Less noise
• More Flexible in layout
• Less loss in communication
20. DRAWBACKS
• Today’s materials require much high power to work in
consumer products, coming up with the right materials
may take five years or more.
• Optical computing using a coherent source is simple to
compute and understand, but it has many drawbacks
like any imperfections or dust on the optical
components will create unwanted interference pattern
due to scattering effects.
• Optical components and their production is still
expensive
• New expensive high-tech factories have to be built
21. FUTURE TRENDS
• The Ministry of Information Technology has
initiated a photonic development program. Under
this program some funded projects are continuing
in fiber optic high-speed network systems.
Research is going on for developing new laser
diodes, photo detectors and nonlinear material
studies for faster switches.
22.
23. CONCLUSION
Research in optical computing has opened up new
possibilities in several fields related to high
performance computing and high-speed
communications.
To design algorithms that execute applications
faster, the specific properties of optics must be
considered, such as their ability to exploit massive
parallelism and global interconnections.
As optoelectronic and smart pixel devices mature,
software development will have a major impact in the
future and the ground rules for the computing may
have to be rewritten.
