Kyocera and Tohoku University developed a world-first laser method to cut back-reflected light by 95% on silicon photonics chips.
Back-reflections can destabilize lasers and degrade performance in photonic integrated circuits.
The breakthrough could help overcome the lack of practical on-chip optical isolators.
Further work is needed to scale the method for commercial manufacturing and verify long-term reliability.

EPFL researchers led by Hatice Altug built mid-IR metasurfaces on suspended membranes of crystalline silicon.
Tuning is achieved by inducing mobile electrical charges in the silicon, changing optical response in real time without altering the nanostructure.
The team demonstrated two tuning approaches, one using integrated electrodes as microheaters.
Switching speeds reach billionths of a second, compared with millisecond-scale tuning in earlier approaches.
