Coherent Cherenkov radiation and laser oscillation in a photonic crystal
| Abstract | We demonstrate that photonic crystals can be used to generate powerfuland highly coherent Cherenkov radiation that is excited by the injectionof a beam of free electrons. Using theoretical and numericalinvestigations we present the startup dynamics and coherence propertiesof such a laser, in which gain is provided by matching the optical phasevelocity in the photonic crystal to the velocity of the electron beam.The operating frequency can be varied by changing the electron beamenergy and scaled to different ranges by varying the lattice constant ofthe photonic crystal. |
