1-D photonic crystal based dynamic encoder/decoder for 2D W-T OCDMA system

Abstract

We propose a novel low power and simple incoherent 2D optical code division multiple access (OCDMA) system comprising of reconfigurable encoder based on voltage dependent wavelength selection in the electro optic (EO) polymer infiltrated silicon photonic crystal and a tunable decoder based on silicon 1-D photonic crystal structures. Using simulation, the power efficient and error free system functioning of the encoding/decoding devices is verified. Dynamic provisioning of code patterns are possible using a single physical implementation of optical encoder/decoder and it can support flexible data rates of about 200 Gbps by using only 4 pair of wavelengths.
