Novel schemes, for V-band (60-GHz frequency range) optical millimeter-wave (mm-wave) carrier generation in radio-over-fiber system, are proposed and experimentally demonstrated that are based on injection-locked Fabry-Pérot laser diodes. Dual-parallel and cascaded structures are individually proposed to generate the mm-wave carrier. We could improve the suppression ratio (SR) of the carrier suppressed optical signal as well as reduce RF phase noise of the mm-wave carrier by using the proposed schemes. The SR improvement of the carrier suppressed optical signal of 20 dB was verified. 60-GHz mm-wave carrier of enhanced signal quality could be also achieved. Its peak power and RF phase noise were obtained as about -40 dBm and less than -95 dBm, respectively, which was suitable for 60-GHz data transmission.
