Demonstration of integrated O-band multi-tip SiN edge couplers with sub-1 dB loss and high power handling.
We demonstrate monolithically integrated O-band Vgroove-based multi-tip SiN edge couplers with 0.5/0.9 dB insertion losses for two polarizations, >280mW power handling and <-40dB back reflection at 1310 nm.
