The wide-angle perfect absorption based on the optical Tamm states

Based on the optical Talnm states （OTSs）, a metal-distributed Bragg reflector （DBR） structure is presented. The existence of optical Tamm states is demonstrated by the dip of reflectivity spectrum in photonic band gap. The properties of the optical Tainm states are investigated by applying the trans...

Summary:Based on the optical Talnm states （OTSs）, a metal-distributed Bragg reflector （DBR） structure is presented. The existence of optical Tamm states is demonstrated by the dip of reflectivity spectrum in photonic band gap. The properties of the optical Tainm states are investigated by applying the transfer matrix method. The effects of different metal thicknesses and angles on the absorption are studied by numerical simulation. The wide-angle perfect absorption appears when the metal thickness is 39 nm.
