A 6.6 Gb/s, 1:8 optoelectronic (OE) time demultiplexer was implemented with InP metal-semiconductor-metal switches. These switches were activated sequentially by <25 ps laser diode clock pulses distributed via an optical fiber splitter and delay lines. The demultiplexer capacitive feedthrough was much larger than the switch photoresponse. Therefore we applied a dc bias to obtain a detected clock pulse comparable to the capacitive feedthrough pulse, each alone being an output 0 bit and both in coincidence being a 1 bit with twice the amplitude of a 0 bit. The S/N was 28.5 dB.
