All-optical switching in distributed-feedback muiltiple-quantum-well waveguides.

We discuss experimental results that demonstrate all-optical switching and pulse-routing functionality, at 1.55 um, of nonlinear multiple-quantum-well waveguides equipped with a Bragg grating. Basing on the nonlinear Time-Domain Beam Propagation Method, the switching behavior has been theoretically investigated using a model, developed as part of this work.
