Light bullet supported by parity-time symmetric potential with power-law nonlinearity Academic Article uri icon


  • © 2016, Springer Science+Business Media Dordrecht. Using a similarity transformation, we find the light bullet solution of (3 + 1)-dimensional nonlinear Schrödinger equation with parity-time (PT) symmetric potential. The diffraction/dispersion and nonlinearity coefficients are chosen as longitudinally inhomogeneous functions. We demonstrate how intensity, width, phase, and chirp of the solution are modulated by the variation in diffraction/dispersion and by the choice of PT-potential. Dynamic characteristics of light bullets in media described by exponentially decreasing diffraction/dispersion and periodically modulated systems are illustrated.
