Abstract

Summary form only given. Based on the trial fabrication of an all-optical gating module composed of quantum well saturable absorber switches and a diffractive optic platform, a new scheme of detecting PPM coded picosecond optical data was proposed. The time-windowing gates efficiently suppress ASE noise of preamplifier, and increase reliability. With this mass-producible module the picosecond optics is open for the massive application areas such as local area networks.
