Title
Electrically steered reconfigurable channel waveguide in an active semiconductor slab
Abstract
A self-focused (soliton-like) waveguide that utilizes that carrier-induced nonlinearities of an active GaAs slab structure is described. A quasi continuous wave 900 nm laser beam was used to write the soliton-like waveguide. Steering of the laser beam over a distance of 20 μm at the output face of a 1.7 mm long device was achieved by injecting an electrical current through a triangular metal electrode lying above the path of the optical beam. 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.
