Experimental Demonstration of Holographic Demultiplexer using Volume Diffraction Grating Based on Photopolymer

Open Access Open Access

Abstract

A 42 channel demultiplexer for dense wavelength division multiplexing(WDM) using photopoly-mer volumetric diffraction grating that has excellent optical properties and low cost capability, has been designed and optically demonstrated. From the experimental results, we have obtained the 3 dB bandwidth of 0.18 nm, crosstalk suppression of 20 dB and channel uniformity of 1.6 dB for 50 GHB channel spacing.
