Compact Reflection Bragg Grating Based on Metal-Insulator-Semiconductor Structure

Abstract:

An ultra-compact and broad-band Bragg grating based on hybrid plasmonic waveguide is presented and investigated. The Bragg grating is formed by a semiconductor trip which is separated from a metal surface by a nanoscale insulator layer. Simulation results demonstrate that the proposed structure shows the capability of efficient wavelength selection near the telecom bandwidths and transmits the light with a strong mode confinement and low propagation loss. It will have a potential application in the broad-band telecommunications systems and the integrated photonic circuits.
