Large-scale Dirac electromagnetic apertures
Abstract
The 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 det,ection and ranging (LIDAR), or communications. We propose Dirac electromagnetic aperture that can scale to large area while maintain,ing 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, es,pecially where power scaling has been a roadblock. The project will design, fabricate, and characterize Dirac electromagnetic apertu,res that are addressed both optically and electrically. The research will 1) investigate the physics of Dirac electromagnetic apertu,res, 2) fabricate and characterize Dirac electromagnetic apertures-based sources 3) realize electrically addressed Dirac electromagn,etic apertures and investigate 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 laboratori,es. The project bridges the fields of topological physics, high-power diodes, and nanophononics, and requires theory/simulation, nan,ofabrication, and characterization.
