Title

Optically induced waveguiding in semiconductor optical amplifiers

Abstract

Soliton waveguiding effects are investigated in an active double heterostructure diode structure used as a nonlinear medium. It was observed that the nonlinearities due to reverse band filling in active semiconductor amplifiers give rise to a spectral region where self-focusing takes place for photon energies very slightly below the energy corresponding to the peak of the gain. By monitoring the mode profile at the output of the slab waveguide either as a function of input intensity or as a function of wavelength, a distinct narrowing of the output beam lateral dimension was observed, and the resulting beam profile remained stable for a wide range of input intensities.
