APDs are photodiodes with internal gain produced by the application of a reverse voltage. They have a higher signal-to-noise ratio (SNR) than PIN photodiodes, as well as fast time response, low dark current, and high sensitivity. Spectral response range is typically within 200 to 1150 nm.

2022年11月13日 · 2019年，美国宇航局的孙晓丽、克雷蒙斯等人开发了一套线性模式单光计数HgCdTe APD焦平面阵列， HgCdTe APD阵列使用高密度垂直集成光电二极管架构，如图3所示。

We report Ge-on-Si APD arrays with up to 10-by-10 pixels at 1550nm. Our demonstration reveals highly uniform responsivity of ~3.3 A/W with <;7% variation. The bandwidth is 9GHz and 0.7GHz for single and 10×10 array.

Avalanche photodiode arrays (APD arrays) These avalanche photodiodes were developed specifically for LIDAR applications and laser rangefinders. The series of products contains linear and matrix arrays with multiple sensors on one monolithic die, e.g. 8, 16, 64 pixels.

Typically used in Time-of-Flight (TOF) sensors for distance measurement, for example in automotive safety sensing applications, linear APD arrays are now available from Laser Components. Combining low-noise, high-sensitivity silicon avalanche photodiodes in a monolithic assembly, the arrays have been optimized for the 800-900 nm wavelength range.

An avalanche photodiode (APD) is a pn junction designed to support high electric fields that cause the primary photogener- ated carrier to initiate an avalanche, that is, a chain of impact

2025年1月14日 · This paper presents two novel avalanche photodiode (APD) array structures designed to significantly enhance both detection area and bandwidth, overcoming the common trade-off between these parameters in conventional photodetectors. The impact of various parameters on the bandwidths of the two distinct array structures was theoretically simulated. Experimental validation using the self ...

2018年11月5日 · Owing to the advantages such as internal photoelectric gain, small size, low driving voltages, high efficiency, and fast response, focal-plane APD arrays bring about new three-dimensional (3D) imaging techniques which provide much wealthier and more accurate information for object recognition and identification .
