Transverse localization of Tamm plasmon in metal-DBR structure with disordered layer Project supported by the National Natural Science Foundation of China (Grant Nos. 61575040 and 61635005) and the 111 Project, China (Grant No. B14039). |
(color online) Far-field intensity pattern without and with consideration of gain in the random layer of case 3, and air in the random layer is replaced by a medium whose refractive index is 1.31 in the case without consideration of gain (ω is azimuth angle) |
