High-Power High-Speed Schottky Photodiodes for Analog Fiber-Optic Microwave Signal Transmission Lines

Abstract

Design and manufacturing technology of high-power microwave Schottky photodiodes with microstripe leads have been developed based on an InAlAs/InGaAs heterostructure. The operating frequency of photodiodes with a mesa diameter of 15 μm is above 25 GHz and a maximum output microwave power at 20 GHz exceeds 50 mW, which allows these photodiodes to be employed in analog fiber-optic microwave signal transmission lines, as well as for the microwave signal generation and processing by optical methods in remote sensing and measuring microwave technology.
