2D FDTD for observing coupling of light in ring resonator structureWritten for Course :-Computational Electromagnetics, Fall 2011Department of Electrical EngineeringIndian Institute of Technology Madras (IITM)Chennai - 600036, IndiaAuthors :-Sathya Swaroop Ganta, B.Tech., M.Tech. Electrical Engg.Kayatri, M.S. Engineering DesignPankaj, M.S. Electrical Engg.Sumantra Chaudhuri, M.S. Electrical Engg.Projesh Basu, M.S. Electrical Engg.Nikhil Kumar CS, M.S. Electrical Engg.Instructor :-Dr. Ananth KrishnanAssistant ProfessorDepartment of Electrical EngineeringIndian Institute of Technology MadrasIn 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 isobserved.
