A novel three-wave mixer is described in which two optical beams are mixed with an RF signal to produce another RF signal. These devices can be used for coherent/heterodyne detection of optical signals with gigahertz frequency offsets. The device consists of a photoconductor embedded in a coplanar microwave circuit
