| 摘 要： | 本文从平面波理论出发,研究了薄膜为非线性介质的对称平板漏波导的TE_0模传输特性.计算结果表明,膜厚大于一临界值时,不存在稳定的TE_0模,膜厚小于临界值时,最多能存在两种峰值场强的TE_0模.膜厚越小,两种峰值场强相差越大.

| Abstract: | Based on plane wave theory, the propagation characteristics of TEo modes have been studied in a symmetric slab leaky waveguide of a nonlinear djelectric film. Our results show that steady TEo modes can not exist if the film thickness is above a critical value, two TEo modes with different peak field intensities may exist at most if the film thickness is below the critical value. With the decreasing of the film thickness, the peak field intensity difference between the two modes becomes large. |
