Abstract

Systems employing down-conversion detection of radio-frequency-modulated optical signals have generated a need for moderate-frequency (300 MHz) high-current (>100 mA) detectors sensitive in the 920-1650 nm wavelength range.¹ Commercially available detectors fail to fulfill the requirements of such applications due to limitations in their output current, resulting in harmonic distortion of large signals, or power dissipation, resulting in device failure. In this paper we describe an (InGa)As-based photodiode, which has demonstrated continuous 140-mA output current at 2-W power dissipation with 0.97-A/W conversion efficiency at 1320 nm.
