Abstract
A waveguide type photoreceptor device of the present invention comprises a waveguide 16a disposed on a Fe-doped InP substrate, the waveguide including an n-cladding layer connected to an n-electrode, an n-light guide layer, a light absorption layer, a p-light guide layer, and a p-cladding layer connected to a p-electrode, laminated onto one another over the Fe-doped InP substrate, and the ratio of the layer thickness of the thicker one of the n-light guide layer and the p-light guide layer to that of the thinner one being between 1.3 and 5 both inclusive.
