描述 ：-

A 4.65 micron x 4.65 micron structure is taken with 7x7 periodic structures of square dimensions (made of silicon i.e n=3.4) having 0.15 micron as the length of a side as a 7x7 square array at the centre of the domain with a separation of 0.45 micron between neighbouring structure both horizontally and vertically. The region in between and surrounding that of the structures are filled with air of refractive index, n=1. A central horizontal line of 7 periodic structures are removed to form a central wave guide through which the light is guided.
