Abstract :
We report a 10-Gb/s hybrid APD-HEMT optical receiver employing a lossless tuned noise-matching technique between an APD and HEMT amplifier stages for high sensitivity and a transimpedance feedback scheme for the wide dynamic range. Measured results show a sensitivity of -29.4 dBm and a dynamic range of more than 29.4 dB, which are the best performances reported to date for 10-Gb/s APD-based optical receivers.
