Abstract

We demonstrate error-free 1.244-Gbit/s ASK data transmission based on remote frequency up-conversion technique in 60-GHz-band radio-on-fiber systems. For frequency up-conversion, 63-GHz optical heterodyne LO signals are cross-gain modulated by another optical baseband signal in SOA, and up-converted signals are generated after photo detection. The dependence of BER characteristics on the power and wavelength of optical baseband signals and the power of optical LO signals is also investigated
