High-Power Bound state In the Continuum Laser.
Abstract
High-power lasers are fundamentally important for many industrial, defense, and scientificapplications. While significant progress"" has been made on fiber based high power lasers, singleaperture lasers have suffered from their limited scalability. We propose a n"ew type of high-powersingle 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 curiosityin quantum mechanics, have recently been demonstrat"ed to make lasers with unique scaling of thequality factor. BIC is a new and more efficient way to trap light in which interference in openphotonic systems in a continuum surprisingly lead to bound electromagnetic states with infinitequality factor. The scaling of BIC photonic modes enables large single apertures that in turn leadsto much higher output power compared to what has been possible so far to reach the kilowattregime at a single wafer scale. These sources will find applications in many Navy systems wherehig"h power is required. The proposal requests $707,940 to design, fabricate, and characterize nextgeneration high-power BICSELs. The r""esearch will 1) investigate the physics of high-powerBICSELs, 2) fabricate and characterize high-power BICSELs and 3) realize elect""rically pumpedhigh-power BICSELs. The project objectives will be accomplished by combining expertise in thedesign, the fabrication"", and the characterization of nanophotonic devices. The project bridges thefields of mathematics, high-power laser physics and phot""onics and requires theory/simulation,nanofabrication, and characterization.
