Abstract :
A new optical receiver is proposed incorporating an InGaAs-transferred-electron device with Schottky gate-electrode (STED) and an InGaAs-metal-semiconductor-metal detector (MSM). This photoreceiver is applicable to the detection of digital, intensity modulated signals and can be integrated on an InP-substrate. The monolithically integrated circuit has been fabricated. Both the integrated STED and the MSM detector has been characterized. From the measurements the receiver can be expected to offer high current gain and inherent pulse shaping. Based on experiments the sensitivity and the gain of the photoreceiver as a function of the bit-rate has been calculated
