Popis: A fast, non-interferometric measurement technique that allows the frequency-dependent delay and amplitude responses to be measured is presented. For a single amplitude and relative phase measurement at a fixed optical wavelength, the measurement time is on the order of a microsecond. RF modulation up to 2.7 GHz can be accommodated. A modified technique using frequency modulation is described to overcome non-idealities in the phase measurement. Results are presented for a fiber Bragg grating and an acetylene gas cell with swept-wavelength laser tuning at a rate of 40 nm/s.
