Abstract :
A fiber optic microwave link with a monolithic integrated optoelectronic mixing receiver (OEM) is demonstrated experimentally. The OEM consists of a GaAs metal semiconductor metal photodetector (MSM-PD) mixer and a MESFET transimpedance preamplifier. By modulating the bias of the MSM-PD with an electrical local oscillator, the information signals on an optical carrier are detected and converted to a desired electrical frequency simultaneously. Experimental results of a fiber optic microwave link with the OEM as a frequency up-converter are shown and the potential application of the OEM in fiber optic millimeter wave links is discussed
