A 56Gb/s 300mW Silicon-Photonics Transmitter in 3D-Integrated PIC25G and 55nm...aiclab
The ever-increasing data center IP traffic, up to 8.6 zettabytes per year by 2018 with nearly 3× growth since 2013 [1], requires power-efficient high-speed interconnects. Next generation optical interfaces will adopt 50Gbaud signaling [2], and minimizing power consumption is key to enable the use of small form-factor optical modules for electro-optical conversion. In this perspective, silicon photonics is an attractive alternative to discrete photonics, lending itself to higher miniaturization at reduced cost [3]. Furthermore, silicon photonics enables co-design of electronics with photonics, thus optimizing transceiver power efficiency. In particular, the electro-optical transmitter constitutes the main source of power consumption. Travelling wave Mach-Zehnder modulator (MZM) architectures are used in discrete photonics realizations as data rate increases, and lend themselves to silicon photonics. However silicon photonics suffers from electrical propagation losses and bandwidth limitations of integrated transmission lines, requiring equalization in the electronic driver to address 50Gbaud operation at moderate consumption and also in advanced node technologies. In this work, we employ a bifilar transmission line determining an electrical propagation loss of ~3dB/mm at 28GHz. Using an equalizer counteracts its effect, applying passive boost and shunt peaking in the pre-driving stage, combined with passive peaking in the load coupling. A 75% increase in the vertical aperture of the optical eye diagram is thus achieved with no power consumption penalty due to the equalizer. The complete electro-optical transmitter, operating at 56Gb/s at 1310nm wavelength, dissipates 300mW and ensures an extinction ratio (ER) higher than 2.5dB. This 56Gb/s silicon photonics transmitter displayes more than 30% power savings with respect to the state-of-the-art [4].

Wideband CMOS Power Amplifiers Design at mm-Wave: Challenges and Case Studiesaiclab
Constant striving towards higher data rates in modern communication systems and the foreseen revolution related to the forthcoming 5G mobile communications are laying the ground for an explosion of the millimetre-wave radio market. The reason? Frequency bands are wider, less overcrowded, and cheaper. Modulation schemes can be relaxed, while very directive antennas can be exploited to realize radio hops of several hundred meters.
On the other hand, the design of all the involved high frequency components is more demanding. The power amplifier, specifically, is a fundamental block of the transmitter for its impact on the overall performance of the entire system and hence poses severe challenges to the designer.
This workshop addresses the peculiar issues involved in the design of power amplifiers in this high-frequency scenario and compares them to the ones confronted with in the traditional microwave bands.
Experts coming from leading groups actively involved in mm-wave PA design will describe and comment upon solutions of choice and real-world examples, both in compound semiconductors (GaAs and GaN) and in Si-CMOS.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

2. Working Principle
Goniophotometric System carries out measuring methods of fixed location and
rotating luminaires. The measured luminaire is installed on the rotating supporte,
the center of which is in line with the rotating supporter center with the help of Laser
sight. The fixed photometry detector is testing the luminous intensity in various
horizontal directions, while the light source rotating. The mechanical equipment
allows turning the tested luminaires around a vertical axis and a horizontal axis.
When tested luminaires turn around horizontal axis, the detector which is at the
same level with rotating table will measure the intensity of each direction at this
surface. When rotating with vertical axis, the detector will measure the intensity at
the vertical surface. The vertical and horizontal axis can be rotated continuously at
-180°~ +180°. According to the measurement requirements, the system can be
operated in B-β, A-α and C-γ coordinates. When getting intensity distribution data,
computer will calculate other photometric parameters automatically.
Double pillars structure (B-β coordinate system)
This type is applied to fixed grille lamp. The symmetry axis of lamp and the
horizontal of rotating supporter is coaxial, in the B-β coordinate system, and the
two is vertical Cross, in the A-α coordinate system.
Single pillar structure (C-γcoordinate and Conic coordinate)
The single column structure will be gotten when the assistant column is taken down
from double columns structure. This type is applied to fixed tube lamp, spot lamp
etc. The axis radiation of lamp and the horizontal of rotating supporter is coaxial.

5.Laboratory Requirements
Room Requirements according to CIE
Model Dark Room (W*H*L) Operation Room(W*L)
LSG-1800XCCD 4*4*15~30m 3*3m
LSG-1800BCCD 4*2.5*8~30m 3*3m
LSG-1700BCCD 3*2.5*8~30m 3*3m
The wall, ceiling and floor should be all coated with dull black paint or be
covered by black cloth and black carpet.
Air-conditioner should be set in the dark room to control the temperature
around lamps to the standard value upon the CIE requirements

8.Application Software
All control of the Goniospectroradiometer operations can be realized by the software,
including gonophotometer movement, data acquisition and processing, real-time
display on screen, report print and etc, thus enabling the measurement easy and
secure.
This system can export data files as following formats:
This kind of format files can be transferred by other illumination and luminaire
design software such as DiaLux
Application software can also implement essential calculation for lighting design as
iso-illuminance distribution curve on a working plane, luminance limitation curve,
luminaire efficiency, effective beam angle, upward luminous flux ratio, downward
luminous flux ratio, effective luminous flux, utilization factor curve etc.
