【Abstract】 There are two different methods for calculating the loss of an optical waveguide with random surface roughness: coupled mode theory and surface scattering theory. Taking an asymmetric slab waveguide as an example, these two methods are compared and it is found that they are different in principle, but give the same results.更多还原
