摘要：
10 GHz clock recovery from 40 Gbps optical time-division-multiplexed (OTDM) signal pulses is experimentally demonstrated using optical phase lock loop based on a terahertz optical asymmetric demultiplexer (TOAD) with a local-reference-oscillator-free electronic feedback circuit. The clock pulse that was used as the control pulse had energy of 800 D and the SNR of the time-extracted 10 GHz RF signal to the side components was larger than 40 dB. (C) 2003 Elsevier Science B.V.
