Abstract :
An optical waveguide with a high-reflection coating is investigated using the finite-difference time-domain (FD-TD) method. The obtained reflectivities are compared with those from the transmission matrix method. Calculation shows the existence of the field propagating along the coating layers, resulting in deterioration of reflectivity, particularly for TM wave.
