Abstract

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.
