Abstract
A 50–60 GHz continuous wave (cw) millimeter wave (MMW) converted from optical signals was detected by using dielectric materials of various kinds for optical‐to‐radio frequency systems.The converted MMW signals were radiated inside a millimeter waveguide through dielectric materials covering either the top of an optical waveguide or the bottom of an LN substrate and detected by a detector. The detected spectral linewidth of the MMW signals was less than 1 kHz. The power of the MMW signals obtained through the only Teflon or alumina at a 50–60 GHz range was larger than that detected by the strip‐waveguide beyond 5 dBm. When copper plate was inserted between the Teflon and LN substrate, the measured MMW power was larger than that detected by a strip‐waveguide beyond 15 dBm. The power of the MMW signals obtained from the bottom of an LN substrate was larger than that detected at the top of an optical waveguide beyond 5 dBm in the same range. © 2011 Wiley Periodicals, Inc.
