Abstract
Detection in the short-wave infrared (SWIR) offers advantages like reduced solar noise and improved atmospheric transmission. Avalanche photodiodes (APDs) are ideal for low-light detection due to internal gain. While silicon (Si) APDs have low noise, they can't effectively detect SWIR light. Germanium (Ge) is good for SWIR detection but suffers from high noise. Ge-on-Si structure offers benefits like SWIR operation and efficient multiplication. This study showcases room temperature operation of a linear-mode pseudo-planar Ge-on-Si APD with high responsivity, gain, and low noise at 1550 nm. Moreover, a 10-pixel linear array exhibits uniform performance, promising for SWIR detection for potential LIDAR application.
