Paper Abstract
Interdigitated photodetectors that are compatible with a standard commercial monolithic microwave integrated circuit (MMIC) process have been designed and characterized. A wide variety of interdigitated metal-semiconductor-metal designs were investigated by varying device geometry and type of contact (Schottky and ohmic). The Schottky photodetector devices exhibited quantum efficiencies between 40 percent and 50 percent with 3 dB bandwidths up to 12 GHz and dark currents less than 5 nA. The fastest device, having 0.5-micron fingers with 1.0-micron spacing, had a useful operating bandwidth up to 40 GHz. The impedance of the photodetectors was measured and equivalent circuit models were derived from the data.
