Abstract

Summary form only given. In future communication systems with more than a 100 Gbit/s data rate, all-optical signal processing will be important. We have proposed a time-space-conversion optical signal processing that uses an arrayed waveguide grating (AWG) and demonstrated pulse train generation using an amplitude filter. The AWG system can provide a wide time window, compatibility with fiber optics, and compactness. In this study, we report the differential processing of short pulses using AWG with a phase-only filter in order to test the feasibility of extending the AWG system to ultra-high-speed communication.
