A 95‐GHz continuous‐wave millimeter‐wave (MMW) was converted from optical signal by using optical technology for future optical and ubiquitous communications. The optical power of 22.5 mW was injected into optical waveguide in this experiment. The absolute power of the MMW signals measured after the MMW amplifier was about 13 dBm at 95 GHz. The spectral linewidth of the MMW signals was less than 1 kHz, and power fluctuation of the MMW was less than 1.3 dBm over the 75–95 GHz range. © 2008 Wiley Periodicals, Inc.
