High power compact bound states in continuum diodes (UC Berkeley)
Abstract
Compact and high-power diodes are important for many industrial, defense, andscientific applications. Progress has been made on fiber based high power lasers, single aperture lasers have suffered from their limited scalability. We propose a new type of electrically powered diode based on Bound state In the Continuum (BIC). Bound state in the continuum (BIC), initially believed to be a mathematical curiosity in quantum mechanics, have recently been demonstrated to make lasers with unique scaling of aperture. BIC enables more efficient trapping of light in systems where interference surprisingly lead to bound electromagnetic states with unbounded quality factor. The scaling of BIC photonic modes enables large single apertures that in turn leads to much higher output power compared to what has been possible sofar to reach the kilowatt regime at a single wafer scale. These sources will find applications in many Navy systems where high power is required. This proposal will to design, fabricate, and characterize BIC diodes that are injected electrically to enable high power. The research will 1) investigate the physics of BIC diodes, 2) fabricate and characterize BIC diodes and 3) realize electrically pumped BIC diodes with heat management system. The project objectives will beaccomplished by combining expertise in the design, the fabrication, and the characterization of optical devices. The project bridges the fields of high-power diodes and nanophononics and requires theory/simulation, nanofabrication, and characterization.
