Compact 8-wavelength receiver optical sub-assembly with a low-loss AWG demultiplexer for 400-gigabit datacom

摘要

A compact receiver optical sub-assembly (ROSA) for 8-wavelength 400-gigabit links was developed. Wavelength scalability of the ROSA with high responsivity of 0.7 A/W was achieved with a low-loss multimode-output arrayed waveguide grating.
