Abstract

We have developed a technique to produce precise fiber-optic time delays with subpicosecond accuracy and <0.1-dB loss by heating and stretching optical fiber in a fusion splicer. A fiber Mach-Zehnder interferometer allows 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 feedforward 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.
