Abstract :
A novel technique for detection of the time delay between optical input signal data and a clock, suitable for applications to phase-locked loops, is investigated with respect to its sensitivity. This pulse timing measurement scheme, which is based on heterodyne cross correlation employing passive optical mixing, is virtually independent of the bit rate. Experimental results in good agreement with theoretical predictions reveal some characteristic properties of the dynamic range of the present timing measurement technique.
