Abstract
To increase the bit rate of wavelength division multiplexed optical data switched in a photonic switching matrix, whilst maintaining a high bandwidth, a wavelength selector and converter includes a demultiplexer with n outputs respectively connected to n inputs of a coupler via n wavelength converters. Each wavelength converter has an optical gate function and selectively supplies converted signals conveyed by the same wavelength. Applications include optical packet switching.
