Abstract
Geiger mode avalanche photodiodes (GmAPDs) are a core component in some optical communications, quantum computing, and lidar systems. Many current efforts are focused on shrinking these devices, specifically for space-borne applications. However, there is a limit to this approach as it also shrinks the photo-active area. The active area of a GmAPD can be reduced without negatively affecting the detector performance, as long as the optical beam can be focused onto a region of the GmAPD with uniform PDE. Using Silvaco’s TCAD software, we model varied diameter mesa type APDs and determine the simulated active area. Next, we describe an experimental setup to measure the active area of a GmAPD with submicron precision. We present initial measurement results scanning across single pixels and compare these results to our simulated TCAD data.
