Efficient Absorption Enhancement Approaches for AlInAsSb Avalanche Photodiodes for 2-μm Applications

We describe two approaches to enhance the quantum efficiency of AlInAsSb APDs for 2-μm detection. Finite-difference time-domain simulations show the absorption at 2 µm can be enhanced by more than 100 % with a photonic crystal, and 400 % with a metal grating.
