Polarization Analyzer Based Detection Schemes for Pol-Mux Self-Coherent Single Sideband Optical Transmission

Case ID:

Researchers at the University of Arizona have developed an orthogonal frequency division multiplexing (OFDM) optical communication system for access networks that can work in a direct receiver mode and in a coherent receiver mode. Compared to currently available OFDM products, the novel system has fewer components and is simpler to set up.

OFDM technology is used to transmit subcarrier frequencies, thereby creating a larger bandwidth.  Systems can either use a direct receiver (amplitude only) or a coherent receiver (amplitude and phase), but not both.
