Optical Tamm state theory study on asymmetric DBR-metal-DBR structure
Acta Physica Sinica, 2013 As a special metal surface state, optical Tamm state (OTS) has been widely used in designing the new generation of optical devices for its unique advantages in light control and operation. Based on distribute Bragg reflector (DBR)-metal-DBR (DMD)structure, asymmetric mechanism is introduced by mismatching central frequencies of the two DBRs to design ...
