Design of Optical Star Coupler for 3D OCDMA System
3D OCDMA coding schemes have been proposed recently supporting more subscribers than conventional 2D & 1D techniques. This is achieved by employing or taking the relaxation with the third degree of freedom i.e. employing temporal, spectral and spatial domains. This paper is to design a star coupler for 3 Dimensional (3D) encoding based on mathematical models A and B as proposed earlier by the authors. Optical star coupler uses multiplexer and demultiplexers for OCDMA system.
