Abstract

In this study, we aim to investigate the interrelation between excess noise and bandwidth in avalanche photodiodes to explore the realization of devices with high gain-bandwidth product. Through comprehensive research and theoretical analysis, it has been determined that, regardless of the operating wavelength and temperature, HgCdTe avalanche photodiodes exhibit favorable characteristics, such as low excess noise and high bandwidth, owing to the phenomenon of single-carrier avalanche multiplication process. Consequently, they represent the optimal choice for high-performance avalanche detection.
