  • 1. Middle Infrared Broadly Tunable Compact Cavity- Camille-Sophie Brès Less Source based on Parametric Conversion Challenge Approach Creation of a Middle infrared (Mid-IR) source to enable the Two-step approach for efficient conversion of Near IR light to Mid-IR: exploitation of the Mid-IR spectral band full potential in Science and Engineering applications (spectroscopy, sensing, free space communication) Silica Soft glass Silicon Near IR Short wave IR Mid-IR GoalsØ  Revolutionize light generation in the Mid-IR band (2 - 6 µm) Ø  Relax phase matching constraintsØ  Move beyond limitations of conventional resonant (cavity) Ø  Utilize advanced Near IR technology with silica front-end processes Ø  Exploit the Mid-IR capabilities of non-silica platformsØ  Develop first modulation capable, portable and athermal §  Design and modelling §  Fabrication source across wide range of Mid-IR frequencies §  Characterization §  Block integration Matisse Agenda Impact Silica front-end Mid-IR stage Two-step mixing Bridge the technological gap between telecom and Mid-IR band   Balancing Material, dispersion Synergy between Provide presently non-existing but essential Mid-IR source  birefringence, loss & engineering & phase telecom devices & dispersion matching physic Mid-IR mixers Mode-hop free operation Sensing§  Near IR quality in §  Engineering novel §  Integration of Broadly tunable short wave IR for non-silica platforms distinct but Narrow linewidth Wideband sensing driving Mid IR driven from short complementary High resolution mapping Modulation capability stage wave IR blocks§  Modulation, §  Efficient wavelength §  Continuous Mid IR spectroscopy Free space communication narrow linewidth, conversion to Mid- coverage over power at silica IR maintaining Near unprecedented Enhanced selectivity Modulation speeds transparency limit IR quality spectral bandwidth Single molecule sensitivity Improved quality
