Paper Abstract

For the first time, we show that soliton switching in semiconductor nonlinear directional couplers without the detrimental pulse break up can be achieved by properly tailoring the waveguide configuration. In particular, we exploit the unusual dispersion characteristic of Anti-Resonant-Reflecting-Optical Waveguides to overturn the normal group velocity dispersion in semiconductors below half-the-band-gap. The coupled set of modified Nonlinear Schrodinger equations is derived and solved by using the Beam Propagation Method.
