Unidirectional Spaser in Symmetry-Broken Plasmonic Core-Shell Nanocavity
The spaser, a quantum amplifier of surface plasmons by stimulated emission of radiation, is recognized as a coherent light source capable of confining optical fields at subwavelength scale. The control over the directionality of spasing has not been addressed so far, especially for a single-particle...
