Lunch Chat: Low-loss gallium nitride integrated photonics

Tue, 11.06.2024, online


We are pleased to announce and invite you to one of our weekly online zoom events.

Low-loss gallium nitride integrated photonics

Gallium nitride, the world’s second most manufactured semiconductor, exhibits advantageous optical properties for photonic integrated circuits but remains relatively unexplored by the R&D community.  In our talk, we will discuss the historical limitations of gallium nitride as a photonic material, progress toward C-band microresonators with quality factors exceeding 10^6, and a vision for GaN as a nanophotonic platform
