SEMICONDUCTOR LASERS Supersymmetric laser arrays

     

摘要

Supersymmetry (SUSY) emerged within particle physics as a means to relate two fun dame ntally different classes of elementary particles: bosons (integer spin, Bose-Einstein statistics) and fermi on sfhalfintegerspin, Fermi-Dirac statistics). Exte nsions to the Standard Model have also been proposed based on SUSY theory in order to resolve Iong-standing issues in quantum field theory, including the nature of vacuum energy, origin of mass scales and dark matter. Even though the experimental validation of SUSY is still an ongoing issue, supersymmetric/ isospectral techniques have already found applications in low-energy physics, nonrelativistic quantum mechanics, and nonlinear dynamics, to name a few. On the other hand, waveguide laser arrays have been a subject of intense investigations for the purpose of building high-power phaselocked lasers, which are immune to the detrimental effects of nonlinearities orfilamentation. Nevertheless, such systems suffer from multimode operation, which in turn leads to a chaotic emission.
