Abstract :
A traveling-wave electroabsorption modulator is used to simultaneously demultiplex and electrically detect a single 10-Gb/s channel from a 20-Gb/s optical time-division multiplexed data stream while transmitting the other channel in an optically transparent manner. A bit-error-rate penalty of 0.5 dB and an error floor were observed for the dropped channel due to residual absorption of the other channel. Error-free operation was achieved for the transparent channel.
