160-Gb/s optical OFDM demultiplexer based on photonic ring resonators

A novel all-optical OFDM demultiplexer based on integrated photonic ring resonators (RR) is proposed and its performance validated. The proposed optical OFDM demultiplexer overcome the processing speed limits introduced by electronics and is suitable for very large scale integration, providing a compact and cost-effective solution. The performance of this device considering a Silicon-on-Insulator (SOI) platform has been demonstrated by demultiplexing a 160-Gb/s (4-subcarrier × 40-Gb/s) OFDM signal. Simulations results show excellent BER performance with error-free operation for each demultiplexed subchannel.
