Paper Abstract

This paper reviews recent progress on high-speed technologies for optical transmission systems in the IP and FTTH era. First, we describe our latest research results of 160 Gbit/s optical time-division multiplexing and demultiplexing experiments. The all-optical time-division multiplexer is realized as a hybrid integrated device consisting of planar lightwave circuits (PLC's) and highly-nonlinear periodically-poled lithium niobate (PPLN) waveguides while the demultiplexer is realized as a hybrid integrated device consisting of PLC's and semiconductor optical amplifiers. A new type of all-optical switch that uses a photonic crystal nanocavity and an all-optical flip-flop circuit that is composed of two-port resonant-tunneling filters based on a two dimensional photonic crystal slab with triangular air-hole lattice are shown. Finally, the possibility of over 100 Gbit/s all-optical signal processing is discussed for high-speed optical transmission systems.
