| 摘 要： | 利用角谱表示和逆规则傅里叶模式理论,研究了非匀幅光束的典型代表TE线偏振高斯光束在亚波长三角形面型浮雕光栅体内的传输.数值分析表明浮雕层内不同透射深度处的光强分布随着透射深度的变化而变化.最后讨论了入射角、周期等光学参数对出射光强分布的影响.这些结论对高衍射效率亚波长光栅的制作和高功率激光光学元件设计等都具有现实意义.

| Abstract: | Based on the angular spectrum representation and the inverse rule Fourier mode theory,the propagation of the super Gaussian beam through the sub-wavelength triangle relief grating is studied.Numerical calculation shows that the distribution of intensity in different penetration depths changes with the penetration depth in the relief layer.The article also discusses the effects of incident angle,period and other optical parameters on the distribution of the outgoing light intensity. |
