Abstract

We experimentally demonstrate a tunable and reconfigurable optical discrete Fourier transform (DFT) to demultiplex orthogonal-frequency-division- multiplexed subcarriers with 2/3/4 subcarriers at 20=40 GHz frequency spacing. An average power penalty of ~5 dB (~3.5) at bit error ratio of 10-9 is achieved for 4 × 20 Gbit/s (4 × 10 Gbit/s) OFDM signal with 20 GHz frequency spacing.
