Description :-

A 20 micron x 8 micron platform is taken with a parallel horizontal ridge waveguide (made of silica i.e n=1.5) of 1 micron width and 20 microns length lying on the centre of the 8 micron width of the platform. The region surrounding the waveguide are filled with air of refractive index, n=1.
