摘　　要：用转移矩阵法数值分析了芯区和衬底为非线性介质、覆盖层为线性介质结构平面光波导的传播特性,包括TM的模场分布和功率与有效折射率之间关系的分析.解析地表达了模式本征方程和功率分布,对非线性介质中电场强度与介质非线性系数的关系进行了研究.计算结果表明,TM的模场分布和功率与有效折射率及介质的非线性系数有关.Propagation properties of TM mode in planar optical waveguide with linear cladding and nonlinear core and substrate are numerically analyzed by transfer matrix method. The study mainly involves in the electric field distributions and optical power on effective index in planar waveguide. The mode eigenvalue equation of TM and expression of laser power are presented, and the effect of nonlinear coefficient on electric fields of TM is investigated. The numerical calculation results show that the electric field distribution and optical power depend strongly on effective index and nonlinear coefficient.
