| 摘 要： | 提出了一种计算有源腔模式分布的有限元数值矩阵方法。对腔镜进行基于菲涅耳–基尔霍夫衍射积分定理的有限元划分,利用MATLAB计算出光一次往返的传输矩阵。然后根据自再现理论,求出矩阵的特征值和特征向量。从而确定谐振腔的模式分布,给新型谐振腔的研究带来极大方便。

| Abstract: | A numerical matrix method for calculation of optical resonator modes with media inside is proposed. The transmission matrix of an optical resonator is obtained by dividing the mirror into finite grids based on Fresnel-Kirchoff diffractive integral equation. Then according to self-recurrence method, eigenvalues and eigenvectors, can be calculated by solving the transmission matrix, which define the distribution of modes of optical resonator. This method will greatly benefit the research of new resonators. |
