In optical fiber communications, variable delays are required for coherent receivers and in the context of time division multiplexing. In an optical autocorrelator, one requires a variable time delay for controlling the relative timing between two ultrashort pulses. A detector signal is then measured as a function of that relative timing. Frequency-resolved optical gating works similarly, only ...
