Optical demultiplexing system |
摘要 |
Optical demultiplexing system, wherein from an optical carrier modulated by a TDM data flow the wanted tributary is extracted as an optical signal. The system makes use of a semiconductor optical amplifier, whose gain is modulated due to saturation effect. The amplifier receives both the modulated optical carrier and one or a plurality of sampling optical carriers, with wavelengths different from that of the modulated carrier. One or a plurality of optical filters supply at the output the tributaries by extracting from the amplifier output the sampling carriers modulated by data signals.
