Scalable Berkeley Surface Emitting Lasers
Abstract
Approved for public release.PROJECT SUMMARYThe question of the scaling of single electromagnetic apertures for high-power lasers has been a long-standing question. Such single-aperture lasing system would have applications in various areas including directed energy, materials processing, sensing, light detection and ranging (LIDAR), or communications. Scale-invariant lasers known as Berkeley Surface Emitting Lasers (BerkSELs) were recently discovered. They are based on open-Dirac electromagnetic singularities that can scale to large area while maintaining the properties of selected optical modes. The proposed electromagnetic apertures have unique scaling properties governed by the topology of the aperture. This project will investigate the physics of such apertures as well as their experimental realization. The project will implement sources based on Dirac electromagnetic apertures that can have numerous applications across Navy systems, especially where power scaling has been a roadblock. The project will design, fabricate, and characterize Dirac electromagnetic apertures that are addressed both optically and electrically. The research will 1) investigate various designs of BerkSELs, 2) fabricate and characterize BerkSEL sources 3) realize electrically addressed BerkSEL devices and implement heat generation and management systems. The project objectives will be accomplished by combining expertise in the design, the fabrication, and the characterization of optical devices in collaboration with DoD laboratories. The project bridges the fields of topologicalphysics, high-power diodes, and nanophononics, and requires theory/simulation, nanofabrication, and characterization.
