Description :-

In this program, a 3.05 micron X 3.6 micron domain is taken with a 450 nm thick horizontal straight waveguide placed in the upper part at a distance of 300 nm from the top. A 450 nm thick ridged circular waveguide with a central radius of 1 micron is placed at a distance 100nm below the straight waveguide. Both the waveguides are made of material of relative permittivity 6. The surrounding area is free space of relative permittivity 1. A sinusoidal source of light of free space wavelength 1.753 microns is excited at the left end of the straight waveguide as a line source along the width of the waveguide. Light is guided through the straight waveguide and coupling into the circular waveguide and its accumulation in it is
observed.
