Nonlinear structures in a wide-aperture semiconductor interferometer when stimulated recombination is important

Concentration - field structures made up of periodically arranged or solitary layers in a thin nonlinear wide-aperture semiconductor interferometer were examined in the range of pumping rates in which stimulated recombination of electrons and holes plays a significant role. It is shown that, after attainment of the threshold concentration in the layers, the latter become microlasers for the transverse wave modes of the interferometer. (nonlinear optical phenomena)
