Abstract
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.
