ANTENNA FEEDBACK SCHEME FOR ACHIEVING NARROW BEAM EMISSION FROM PLASMONIC LASERS |
| 摘要 |
A distributed antenna-coupling feedback scheme and specially designed distributed feedback (DFB) metallic cavity and grating for laser application and in particular to plasmonic lasers ensuring a predesigned phase condition such that a mode traveling inside a waveguide is coupled/phase-locked to a mode traveling on the top metal improving the beam quality of the laser. |

1. A plasmonic laser comprising:
an optical cavity enclosed in a surrounding medium; a metallic cladding surrounding the optical cavity; an optical gain medium enclosed in the cavity; and a periodic structure implemented in at least one of the cladding and the optical cavity, wherein the periodic structure is determined from a phase match condition, such that upon pumping of the gain medium a coupling is established between a first guided electromagnetic wave in the optical cavity and a second guided electromagnetic wave in the surrounding medium. |
