Abstract

We demonstrate experimentally the compression of femtosecond-scale pulses by two-photon gain in a compact electrically driven AlGaAs waveguide. Dynamic control of the pulse width from 240 to 140 fs is achieved by varying the current injection levels—in good agreement with the calculations. The pulse width is measured by a high- sensitivity intensity autocorrelator based on two-photon absorption in a GaAs photomultiplier tube.
