EXPERIMENTAL STUDY OF MULTISTABILITY IN A MULTIMODE VERTICAL CAVITY LASER
Abstract
The coexistence of various spatial distributions of the laser intensity in a multimode VCSEL for fixed DC values has been experimentally demonstrated. These structures are characterized by different integrated intensities, polarization states, and a set of wavelengths. It is shown that the presence of spatial multistability leads to the appearance of multistability in the laser intensity and polarization multistability. The spatial multistability leads to a strong local dependence in the hysteresis behavior of the laser intensity on the pump current. The effect of the temperature of a laser diode on the manifestation of multistability is also investigated.
