Abstract :
We have designed a novel avalanche-free single photon detector for IR wavelengths above 1 μm. The detector shows high quantum efficiency and high gain. A detailed finite-element-method based three-dimensional simulation was developed to model and evaluate the nonlinear effects involved in the design.
