摘要：

An InGaAsP optical waveguide has been used as a combined nonlinear mixer and detector in an autocorrelator for measuring the pulse width of 1.5 mu m wavelength optical pulses. Two-photon absorption in the waveguide provided an autocorrelation current at average-power peak-power products as low as 0.08(mW)(2), thus giving >1 orders of magnitude improvement in sensitivity compared to conventional autocorrelators.
