【Abstract】 The perturbation method is used to study the propagatio characteristic jn the planar waveguide with the second-order polynomial refractive index distribution. The second-order term in the index is considered as perturbation and then the expression of propagation constant is derived. The parameters in the index profile are fit by using the existing experimental data.更多还原
