This work presents a technique for the design of visible optical filters using a hybrid plasmonic insulator-metal-insulator (IMI) structure. The proposed IMI visible light filter exhibits high transmission (∼91%) and an insertion loss of ∼0.4 dB with almost an omnidirectional field-of-view (0°-70°), a feature that is important for light collection in miniaturized devices. The proposed design also has a minimal polarization dependent loss of 0.2 dB at an angle of incidence of 60°. The effects of design parameters on the filter's performance are studied. Design rules of the filter are deduced along with physical justifications of the obtained results.
这项工作提出了一种使用混合等离子体绝缘体-金属-绝缘体（IMI）结构设计可见光滤波器的技术。所提出的IMI可见光滤波器具有高透射率（约91%）和约0.4 dB的插入损耗，几乎具有全向视场（0°-70°），这一特性对于小型化设备中的光收集非常重要。所提出的设计在入射角为60°时还具有最小的偏振相关损耗0.2 dB。研究了设计参数对滤波器性能的影响。推导了滤波器的设计规则以及所得结果的物理依据。
