High Power Metamaterial Laser
Abstract
High Power Metamaterial LaserThe goal of this proposal is to develop high power metamaterials lasers using recent ideas on topological photonics and the unconventional properties of Dirac cones (DC) dispersion. This field was inspired by the discovery of topological insulators, in which interfacial electrons transport without dissipation, even in the presence of impurities. Similarly, the use of carefully designed wavevector space topologies allows the creation of systems that support new states of light. WhileDirac cone is reminiscent of dispersion of electrons in graphene, it can now be use to tam photons, leading to new capabilities for photonic devices. Dirac cones can increase mode spacing by orders of magnitude and thus allow for much larger area surface laser based on metamaterials. The large area in turn leads to much higher output power compared to what has been possible so far. These sources will find applications in many DoD systems where high power is required. The research will 1) investigate the physics of high power metamaterial laser, 2) fabricate and characterize high power metamaterial lasers and 3) realize electrically pumped high power metamaterial lasers. Theproject objectives will be accomplished by combining expertise in the design, the fabrication, and the characterization of nanophotonic devices. The project bridges the fields of topology in mathematics, laser physics and nanophotonics and requires theory/simulation, nanofabrication, and characterization.
