Abstract
The author reports a theoretical study on the photoresponse characteristics of an InP/Ga0.47In0.53As superlattice p + in + APD for operation in the 1-1.6 μm wavelength region. It has been found that the β/α ratio for the structure is 16 for an electric field E =3×107/m. The device is thus expected to become an attractive low-noise detector for fibre-optic communication systems. The device has a quantum efficiency of 60% at λ=1.3 μm. The bandwidth of the response curve is approximately 100 MHz
