Paper Abstract
A high-speed n-GaAs planar Schottky barrier photodetector capable of detecting an analog/digital modulated microwave optical signals up to 20 GHz has been fabricated. The impulse response measurement shows that the photodiode has a risetime of 27 ps and a FWHM of 94 ps. The spectral response measurement yields a responsivity of 0.40 A/W and quantum efficiency of 62 % at 820 nm. Based on the measured RC time constant (C = 0.15 pF and Rs = 7.6 ohm), the photodiode of 25 pm in diameter has a 3-dB bandwidth of 18.5 GHz.
