Co‐packaged datacenter optics: Opportunities and challenges

IET 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

Turbulence‐Resilient Coherent Receiver Array on CMOS‐Compatible Silicon Photonics for Free Space Optical Communications

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
A CMOS‐compatible silicon‐photonic 4 × 4 coherent receiver array spatially samples turbulence‐distorted wavefronts and, with maximum‐ratio combining, enables signal recovery. Experimental BPSK tests under moderate turbulence approach theoretical combining efficiency, reducing BER from 1E‐2 to 1E‐15.

High‐Speed Multimode Fiber Imaging Using Binary‐Modulated Silicon Photonics Optical Phased Array

Laser &Photonics Reviews, Volume 19, Issue 13, July 8, 2025.
A multimode fiber imaging system at 500 frames per second is experimentally demonstrated. It is enabled by a p‐i‐n diode‐based silicon photonics optical phased array. To simplify the electrical driving of p‐i‐n diodes, a binary modulation method with a costumed‐designed digital driver circuit is proposed. Reconstruction of each frame takes only 0.1 ms,
