Abstract

We demonstrate an optically injection-locked self-oscillating optoelectronic mixer (OIL-SOM) for radio-on-fiber downlink applications. OIL-SOM is based on a monolithic oscillator containing an InP-InGaAs heterojunction phototransistor (HPT). The oscillator is OIL by remotely delivered optical local oscillator (LO) signals, and provides low phase-noise and high-power electrical LO signals. In addition, the HPT in this oscillator can simultaneously perform optoelectronic mixing, in which optically transmitted intermediate frequency signals are up-converted to the desired radio-frequency band with high conversion efficiency. With these, OIL-SOM can make base station architecture simple in radio-on-fiber downlink systems. [ABSTRACT FROM PUBLISHER]
