Abstract

We demonstrate an optical orthogonal frequency division multiplexing (OFDM) demultiplexer with an optical discrete Fourier transform circuit fabricated using silica planar lightwave circuit technology. This compact device can process an arbitrary number of subcarriers. The operation of a ten-channel device is demonstrated by demultiplexing a 100 Gbit / s (10 subcarrier × 10 Gbits / s ) OFDM signal. We also discuss a main factor affecting characteristics degradation of the device.
