Abstract :
Photo-absorption characteristics of GaAs0.5Sb0.5 lattice-matched to InP substrate and the DC performance of GaAs0.5Sb0.5/InP pin photo- diodes are reported. The absorption coefficient of GaAs0.5Sb0.5 and the responsivity of the fabricated pin photodiodes were measured to be 6.8 times 103 cm-1 and 0.57 A/W under 1.55 mum radiation, respectively.
