Switching from nonlinear beam focusing to defocusing in periodic structures Conference Paper uri icon

abstract

  • We demonstrate experimentally the transition of nonlinear beam focusing to defocusing by varying the modulation depth of a periodic system. The observed effect illustrates the fundamental crossover when the periodic system changes properties to homogeneous. 2009 Optical Society of America.
