Optical OFDM demultiplexer using silica PLC based optical FFT circuit

We propose an integrated-photonic device for demultiplexing optical OFDM signals that consists of an optical FFT circuit. An optical demultiplexer for four OFDM sub-carriers is realized, and used to demultiplex 4 times 10 Gbit/s signals.
