Silicon photonics for consumer healthcare monitoring
Aaron Zilkie
Rockley Photonics, United States of America
In this presentation I will describe how silicon photonics platform can be applied to imaging and consumer healthcare sensing. I will describe the platform building blocks and capabilities needed from the silicon photonics platform to provide the range of solutions needed for these applications, as well as what are the specific applications that are driving large volume products in this space.

Micro frequency combs for quantum applications
Roberto Morandotti
INRS Montreal, Canada
The development of accessible next-generation
technologies for quantum information science necessitates the
realization and precise manipulation of complex entangled photon
states on practical and scalable platforms. Furthermore, adapting
these quantum photonic platforms to off-the-shelf optical
telecommunications represents an important, yet challenging,
milestone. Quantum frequency combs (QFCs) are a powerful tool
towards this goal, since they enable the generation of complex
photon states in just a single spatial mode as well as their control
through the use of readily available fiber-based telecom
components...

We demonstrate a compact wavelength demultiplexer for the silicon on insulator platform based on the curved waveguide grating (CWG) architecture. We mitigate off-chip radiation loss by enforcing the single beam condition by using metamaterial index engineering. The fabricated device exhibits insertion loss as low as 1dB and crosstalk lower than -25 dB.

We present our latest progress in implementing Bragg filters with a customized spectral response in the silicon-on-insulator platform. Our filter comprises a silicon waveguide with an array of Bragg segments placed aside. The waveguide core is designed to have a reduced mode confinement, which enables an accurate control of the grating strength via modulation of the Bragg segment separation distance and allows for minimum feature sizes compatible with deep-UV lithography. Our design strategy is experimentally validated by demonstrating a filter with 20 non-uniformly spaced notches in the transmittance spectrum.
