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