摘要

Higher emission rates and controllable emission direction are big concerns when it comes to finding a good single photon source.Recently,surface plasmons are introduced to this application,as they can manipulate and enhance the luminescence of single emitters.Here,we experimentally achieve a wide-area multiple directional enhanced light source through periodic metal grating structures.The surface-plasmon-coupled emission can have multiple precisely emission angles by just changing the period of the grating.Our result indicates that metal plasmonic grating can be used as a productive quantum device for unidirectional quantum light sources in quantum optics.
