All-optical switching in a nonlinear GaAlAs X junction.

We demonstrate femtosecond all-optical switching in both symmetric and asymmetric nonlinear X junctions, fabricated in AlGaAs channel waveguides at 1555 nm with photon energies below one half the semiconductor band gap. The switching is a consequence of optically induced symmetry breaking within the junction.
