We study, in this paper, the hysteresis dependence and the number of pulses in steady state as a function of both the small signal gain and the nonlinear coefficient of microstructured fiber.
We have experimentally observed a “backward” (clockwise rotating) hysteresis cycle in the system of an optical ring cavity containing three-level (L-type configuration) rubidium atoms. The shape and
