Temperature effect on a-SiCN:H waveguide for application of sensing

Abstract

In this article, Effect of temperature on a-SiCN:H waveguide is comprehensively discussed. Both absorption and reflection losses of a-SiCN:H waveguide are considered to determine the transmitted energy at wavelength of 632 nm. Transmittance from such construction is simulated using plane wave expansion technique. Simulation output is exposed that transmittance varies linearly with respect to the temperature. It is also observed that absorption of a-SiCN:H is negligible at the wavelength 632 nm. Experimental set up is proposed to compute transmitted energy coming from the same waveguide with respect to various temperatures. Ultimately simulation outcome showed that transmitted energy of such construction varies outstandingly, which is a good temperature sensor
