High-Power Bound State in the Continuum Laser (UC Berkeley)
Abstract
High-power lasers are fundamentally important for many industrial, defense, and scientific applications. While significant 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 high-power single aperture laser based on photonic Bound state In the Continuum Surface Emitting Lasers(BICSELs). 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 the quality factor. BIC is a new and more efficient way to trap light in which interference in open photonic systems in a continuum surprisingly lead to bound electromagnetic states with infinite 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 so far to reach the kilowatt regime at a single wafer scale. These sources will find applications in many Navy systems where high power is required. The proposal requests $707,940 to design, fabricate, and characterize next generation high-power BICSELs. The research will 1) investigate the physics of high-power BICSELs, 2) fabricate and characterize high-power BICSELs and 3) realize electrically pumped high-power BICSELs. The project objectives will be accomplished by combining expertise in thedesign, the fabrication, and the characterization of nanophotonic devices. The project bridges the fields of mathematics, high-power laser physics and photonics and requires theory/simulation, nanofabrication, and characterization.
