Abstract
A photodiode for an input light signal comprising an absorption layer having an absorption coefficient which is less than the absorption coefficient of InGaAs when measured at a wavelength of 1.55 &mgr;m. First and a second cladding layer are disposed on opposite sides of the absorption layer leaving exposed a side of the absorption layer. Positively and negatively polarized contact layers are disposed on the first and second cladding layers respectively. The input light signal is directed into the exposed side of the absorption layer and the absorption layer absorbs the input light signal and photo-generates therefrom carriers. The contact layers collect the carriers and generate therefrom photocurrent.
