Abstract

This work describes the implementation of all-optical switching in distributed-feedback single-mode waveguides having a non-linear multiple-quantum well core. The optical nonlinearity is due to variations of the excitonic optical properties induced by the presence of a carrier plasma, that is photogenerated using a pump beam. We summarize the theory and present results of both static and dynamic experiments, documenting pJ switching energies, bistability and pulse compression, at wavelength of interest to telecommunication applications.
