摘　　要：基于传输矩阵法(TMM)研究了可见光波与棱镜耦合的多层光学薄膜间的相互作用,实现了一种由于共振隧穿导致的带通滤波器。计算得到了复合结构的透射谱线,重点分析了棱镜间空气层厚度对滤波特性的影响。在横电(TE)波入射下,通过优化计算得到目标颜色对应的几何参数。同反射模式下的颜色滤波器不同的是,结构会透过一种特定的颜色并反射光谱的其余部分。优化后得到了红绿蓝(RGB)三色滤波器优化的结构参数,获得了100%高透射率的光谱输出。红色、绿色、蓝色对应的滤波器谐振波长分别为683 nm、517 nm和444 nm。The interactions between visible light wave and the prism-coupled multilayer optical film has been studied based on the transfer matrix method(TMM).A bandpass filter due to resonance tunneling is realized.The transmission spectrum of the composite structure is calculated,and the influence of the thickness of the air gap between the prisms on the filtering characteristics is analyzed.Under the incident light of transverse electric(TE)wave,the geometric parameters corresponding to the designed color are obtained through optimization calculation.Unlike the color filter in reflection mode,the proposed structure transmits a specific color and reflects the rest of the spectrum.After optimization,the structural parameters correspond to the red,green and blue(RGB)three-color filters are obtained with 100%high transmittance.The filter resonance wavelengths for red,green,and blue are 683 nm,517 nm,and 444 nm,respectively.
