| Abstract: | Field distributions of guided TE and TM modes in a multiple quantum well(MQW) waveguide with a saw tooth refractive index profile are calculated by exact method and by method of equivalent refractive index respectively. Numerical examples demonstrate that the solutions of the two methods agree well when the period of the MQW waveguide is small as compared to the core width. This shows that the method of equivalent refractive index to analyze the characteristics of the MQW waveguide is effective. |
