Abstract
A monolithic integrable HEMT photodetector is experimentally investigated for use in fiber optic subearrier transmission links. The frequency response and noise performance of the IIEMT photodetector are discussed in this paper. The results include a response of 1.0 A/W and a signal-to-noise ratio of 49.8 dB (BW = 1 MHz, Popt = ¿8.5 dBm), at a subcarrier frequency of 1 GHz. This photodetector is expected to contribute to high-performance and cost-effective optical/RF transducers.
