Abstract
We have developed a technique to produce precise fiber-optic time delays with subpicosecond accuracy and in situ measurement of these precise delays using a simple alignment process and requiring only a weak optical signal. To demonstrate this capability, we assembled a six-stage feed-forward delay line that can be used to generate 64 optical pulses with 9.5 ± 0.8-ps pulse spacings and 4.8-dB total insertion loss.Keywords
