Abstract
We report what is to our knowledge the first experimental evidence of nonli near beam displacement in a strip-loaded GaAs/AlGaAs multiple-quantum-well waveguide with an asymmetric, nonlinear cladding. An intensity-dependent sp atial displacement of similar to 2 pm was observed for the guided mode at a wavelength of 1.55 mu m. Numerical simulations that correspond to the expe riment are also presented. The device has the potential of providing a soli ton-emission-based, ultrafast all-optical snitch.
