Realisation of Pressure Sensor using one Dimensional Indium Arsenide (InAs) Based Photonic Waveguide in 3 Communication Windows

Abstract

Indium arsenide (InAs) based one dimensional photonic crystal waveguide is cautiously considered in three optical communication windows. Here, the emerging transmitted signal from one dimensional photonic structure is determined with the consideration of five types of losses (diffraction loss, reflection loss, absorption loss, propagation loss, polarisation loss). Further, the transmitted signal is obtained with respect to pressure, which ranges from 0 GPa to 5 GPa for different lattice constant of photonic structure (100 nm, 120 nm, 140 nm). Simulation upshots revealed that indium arsenide semiconductor based photonic waveguide shows an excellent outcome for pressure sensor in the three optical windows as well as different waveguide lengths.
