摘要： A method of extracting a predetermined channel from an OTDM signal includes the steps of combining at the inlet of an SOA the OTDM signal and an impulsive signal with impulses temporally synchronized with the channel to be extracted to produce in the SOA FWM, XGM and XPM effects which shift to a length c the channel chosen for extraction with c outside the length d of the OTDM signal with the other channels outlet from the SOA and filtering the SOA outlet to extract components with c d that represent respectively the desired channel and the cleaned OTDM signal. A multiplexer in accordance with the method includes an inlet (14) of an OTDM signal sent to an SOA (24) together with an appropriate impulsive signal. The SOA outlet is filtered by filters (28, 29) to obtain the signal of the extracted channel (16) and the cleaned OTDM signal (15).

摘要： The present invention relates to Digital-to-Analog conversion in the optical or photonic domain. The present invention pr ovides a digital-to-analog converter (DAC) (100) arranged to receive an N-bit digital optical signal (105) and to process the N-bit digital optical signal to generate an analog optical signal (110). The DAC comprises a photonic circuit (120a, 120b) arranged to adjust the amplitude of each bit of the N-bit digital optical signal dependent on the amplitudes of at least one of the other bits of the N-bit digital optical signal. The amplitudes are adjusted using a non-linear optical effect in order to generate respective outputs for each bit. The DAC also comprises a photonic combiner (145) arranged to combine the outputs for each bit to generate the analog output signal (110).
