Paper Abstract

Two basic parameters, the surface recombination velocity(S) and the diffusion length(Le), have been studied through investigating the responsivity of InGaAs p-i-n photodiodes without an InP window layer. The values of S and Le were found to be 10 4cm/s and 4μm, respectively. The high responsivity of 0.7A/W at λ=1.3μm was obtained without an antireflection coating due to the small surface recombination velocity.
