Abstract

Geiger-mode Avalanche Photodiode (GmAPD) sensors operating in the short-wave infrared wavelength range provide single-photon sensitivity along with precise time-of-flight measurement capability. Cameras built from such sensors are uniquely suited for use in LIDAR systems. We present the development of a computational model of a GmAPD device. We apply this model to identify and optimize key parameters in the epitaxial growth structure, with the goal of producing maximum photon detection efficiency while maintaining a low dark count rate. These simulations suggest a modest design adjustment will result in a relative increase in detection efficiency of more than 15% at typical operating bias voltage, when compared to a legacy control design. A new epitaxial growth and device fabrication campaign has been executed to test the results of the simulation. We will present test results from sensor devices fabricated from both the optimized and control designs.
