Abstract

The efficiency of waveguide InP/InGaAsP(λg =1.3 μm)/InGaAs/InGaAsP(λg = 1.3 μm)/InP p-i-n photodiode is calculated using the step-segment method and overlap-integral between the optical field of a fiber and that of the photodiode. Remarkably high coupling efficiency to a fiber can be obtained by using a multimode waveguide structure. The fabricated device has an external quantum efficiency of 68% as well as a 3 dB bandwidth of higher than 40 GHz at a 1.55 μm wavelength.
