Abstract
Powerful picosecond optical pumping of the GaAs heterostructure layer causes the generation of stimulated picosecond emission in it. Due to its high intensity, the emission induces a Bragg grating of the electron population in the active region of the layer, making the latter an active photonic crystal. In the emission field, the inverse population of electrons oscillates with time, which should lead to spatiotemporal modulation of the emission and this population. It has been discovered that if the distance Y between the end of the heterostructure and the center of the active medium and the geometric parameters of the indicated modulation and movement of emission in the photonic crystal satisfy certain conditions, then dimensional resonance occurs - a maximum of modulation of the dependence of the energy of emission emerging from the end on Y and on pump energy appears locally.
