Abstract
An optical autocorrelator comprises an optical waveguide () of semiconductor material which exhibits two photon absorption at a wavelength at which the autocorrelator is intended to operate. Reflecting means () are provided at a part of the waveguide which is remote to an end () in which an optical pulse () is input for reflecting the optical pulse such as to generate counter-propagating optical pulses in the waveguide. A plurality of electrodes () are disposed along the waveguide for measuring a two photon absorption photocurrent (i-i) generated in the waveguide by the counter-propagating optical pulses.
