Abstract: The injection of two electromagnetic waves into an active quasiwaveguide layer is investigated. It is shown that hysteretic switching of the direction of lasing of the quasiwaveguide layer is possible. A self-trapping effect is identified. The output intensities can exhibit a multistable dependence on the intensity of an input signal.
