InP optoelectronic switches are shown to offer potential performance advantages over conventional diode bridges as electronic mixers. Devices with micrometer-geometry interdigitated-finger structures have been fabricated and tested. The geometry of such structures can be chosen to optimize mixer performance over a wide range of frequencies. Mixer operation has been demonstrated at 100 MHz and calculations indicate good performance into the GHz range with existing InP technology and GaAs diode laser sources.
