Design of microcavity semiconductor devices for highly efficient optical switching and sampling applications (2002)

Abstract Summary form only given. Two Photon Absorption (TPA) in semiconductors has recently been shown to be a serious candidate for optical autocorrelation of short pulses, and all-optical switching and sampling of high speed optical data signals in optical time division multiplexed (OTDM) systems. In this paper we present the design and fabrication of a TPA detector that has been specially designed for TPA with an input wavelength around 880 nm. The device that we have constructed is based on a microcavity structure, which greatly enhances the interaction length. We also demonstrate the use of this non-linear detector for carrying out autocorrelation measurements on picosecond optical pulses.
