In this paper, we have suggest, design, and simulate an all optical 1*2 demultiplexer (Demux) depended on Insulator-Metal-Insulator (IMI) plasmonic multilayer structure. The proposed structure offers operating wavelength at 1550 nm the design area is (350 nm* 350 nm). work, Finite Element Method (FEM) used by using COMSOL Multiphasic software (version 5.4). working principle of device (plasmoni...

Abstract Silicon photonics is an emerging technology which, enabling nanoscale manipulation of light on chips, impacts areas as diverse communications, computing, and sensing. Wavelength division multiplexing commonly used to maximize throughput over a single optical channel by modulating multiple data streams different wavelengths concurrently. Traditionally, wavelength (de)multiplexers are im...
