Abstract

A multiple quantum well layer on top of a dielectric reflector is used as an optical switching device. With a test beam at λt = 868 nm and a 1 mW control beam at λc = 790 nm a switching contrast of 10:1 is achievOd. This high modulation depth is enabled by the coincidence of an excitonic resonance and a Fabry-Perot resonance. Excess carrier lifetimes of a few ns allow for bit rates of ca. 100Mb/s.
