Unidirectional coupling of surface plasmons with ultra-broadband and wide-angle efficiency: potential applications in sensing
A cascaded-grating coupling scheme for unidirectionally coupling and launching surface plasmons from free-space light with ultra-broadband and wide-angle efficiency is proposed and theoretically investigated, and the potential applications in sensing are discussed. The cascaded sub-gratings of diffe...
