Polarization Effect of Antireflection Coating for SOI Material System

For Silicon on Insulator (SOI) material system light transmission& polarization effect due to antireflection coating is investigated with the aid of CAD tool Essential Macleod& MATLAB. In case of one layer coating the transmission is 93.0440 % for TM polarized light and 92.6245 % for TE polarized light after layer thickness optimization. Multilayer coating for SOI material system (using different thicknesses and materials) some time gave identical result and some time less than the transmission got for single layer coating. Average transmission of light is increased about 19 % due to the use of antireflection coating.
