Summary :

In this paper, we report the calculations of the quantum efficiencies of new types of photodiodes that have the ability to demultiplex the incident light beam into two or three independent outputs according to its wavelength, and determine the diode parameters that give maximum efficiency and low crosstalk. Two types of diodes were fabricated with LPE grown InGaAsP/InP quaternary system which is one of the most useful materials in the 1.01.7 µm low-loss spectral window of optical fiber. One diode divides the input light beam into two outputs and the other does in three outputs. The experimentally obtained spectral responses of the diodes were in good agreement with the calculated ones. The fabricated diodes exhibited nearly 100% internal quantum efficiency and crosstalks of 34 dB at λ1.0 µm and below 50 dB at λ1.35 µm, respectively, where the efficiencies of two outputs take their maximum values.
