A general eigen equation has been deduced that can handle ideal and non-ideal quarter-wavelength cases of Bragg-reflection waveguide structure for nonlinear interaction with matching layers on each side of the active region. In particular, this equation allows for solving the cases when the Bragg reflectors are non-ideal quarter-wavelength thick. With this equation, we propose a Bragg-reflection waveguide structure based on the / material system with high figure-of-merit || total nonlinearity and checked the influence if the thickness of the quarter-wavelength Bragg reflectors is off by 10%.
已经推导了一个通用本征方程，该方程可处理布拉格反射波导结构的理想和非理想四分之一波长情况，用于与有源区两侧的匹配层进行非线性相互作用。特别地，该方程能够求解布拉格反射器为非理想四分之一波长厚度的情况。利用这个方程，我们提出了一种基于具有高优值（总非线性）的/材料系统的布拉格反射波导结构，并研究了四分之一波长布拉格反射器厚度偏差10%时的影响。
