摘要： A demultiplexer and method for a high speed time division multiplex optical communication system uses an opto-electronic device in which two photon absorption can occur configured in circuit. The received optical multi-channel signal and a control optical signal at the repetition rate of and synchronised to the selected channel to be detected are applied to the device, which is configured in circuit as to generate by non-linear two photon absorption effect a current similar to the original signal.
