Planar broad-band and wide-angle hybrid plasmonic IMI filters with induced transmission for visible light applications.
Additional Document Info
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 0.4dB 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 0.2dB 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.
