We have proposed an optical spectrum control circuit that realizes various kinds of signal processing in the optical domain using a silica-based planar lightwave circuit including arrayed-waveguide gratings. In order to obtain a flat transmission ...
We propose a cyclic NxN AWG router that can multi/demultiplex upstream and downstream signals with different channel spacings in different wavelength regions. We fabricated a 4x4 AWG router for our novel lambda-tunable WDM/TDM-PON using silica-bas...

We demonstrate an integrated 100GbE receiver optical sub-assembly (ROSA) that incorporates a monolithic four-channel avalanche photodiode (APD) array and a planer lightwave circuit (PLC) based LAN-WDM demultiplexer. A record minimum receiver sensi...
