| dc.description.abstract | We discuss asymmetric reflectance in surface plasmon Bragg gratings incorporating optical gain, referred to as active asymmetric surface plasmon Bragg gratings. It is shown that balanced modulation of index and gain/loss with quarter pitch spatial shift causes unidirectional coupling between contra-propagating modes in long-range surface plasmon polariton Bragg gratings. Such gratings operate at the breaking threshold of parity-time symmetry (exceptional point). Two active asymmetric surface plasmon Bragg gratings designs are proposed and their performance is examined through modal and transfer matrix method computations. ? 2016 SPIE. | - |
