InGaAs MSM photodetectors for long-wavelength fiber communications

摘要

Abstract: We discuss the properties and performance of state-of-the-art barrier enhanced InGaAs metal-semiconductor-metal (MSM) photodetectors, for use at 1.3 $mu@m and 1.55 $mu@m wavelengths. Different device characteristics, such as response, capacitance, and speed, are considered. Integration with transistors of form monolithic receivers and with semiconductor waveguides to form pre-detection optical processing circuits, is also discussed.!8
