CW Emission and Self-Pulsing in a III-V/SiN Hybrid Laser With Narrow Band Mirror [PDF]

open access: yes, 2022
We report on how external cavity III-V/SiN hybrid lasers operate in regimes of ultra-damped relaxation oscillations or in CW unstable dynamical regimes (self-pulsing or approaching turbulence) as a consequence of mirror dispersion, non-zero linewidth ...

Silicon Channeled Spectropolarimeter for On‐Chip Single‐Detector Stokes Spectroscopy

open access: yesAdvanced Photonics Research, Volume 3, Issue 2, February 2022., 2022
This work presents a channeled spectropolarimeter on a microchip using a CMOS‐compatible technology. The device has an ultracompact structure and requires only a single photodetector to recover a broadband full‐Stokes spectrum with a high resolution. This work transforms the paradigm of channeled spectropolarimetry from free‐space optics to integrated ...

Co‐packaged datacenter optics: Opportunities and challenges

open access: yesIET Optoelectronics, Volume 15, Issue 2, Page 77-91, April 2021., 2021
Abstract High‐capacity, high‐density, power‐, and cost‐efficient optical links are undoubtedly of critical importance for datacenter infrastructure. However, the optics roadmap has come to a fork in the road: Is it right to continue on the tried and proven path of pluggable modules or is it time to adopt a new deployment model that involves co‐packaged
