Abstract

We demonstrate an all-optical contention resolution technique that preserves the wavelength of two same-wavelength contending incoming 2.5 Gbit/s channels. This is achieved by optically subcarrier-multiplexing one channel to a higher RF frequency beyond the first baseband channel on the same input wavelength. By using narrow (/spl sim/5 GHz) fiber Fabry-Perot filters for demultiplexing we recovered each channel using a baseband receiver with <1 dB power penalty.
