Modeling of AlInAsSb waveguide avalanche photodiodes for MWIR applications
19 August 2024 • 5:30 PM - 7:00 PM PDT
Abstract
Two-dimensional modeling of AlInAsSb mid-wave infrared waveguide avalanche photodiodes is presented in this work. The waveguide coupling is investigated based on the beam propagation method. The APD photon-response and impact ionization are further simulated based on a drift-diffusion theory. The frequency response and bandwidth are also evaluated. Modeling results of I-V curves, multiplication gain, breakdown voltage, excess noise factor, -3dB bandwidth and gain-bandwidth product are presented with some comparable to the experimental report from other researchers. Design optimization is also explored together with results discussion.
