Abstract
All-optical switching by using a nondegenerate cascaded second-order n onlinearity is described wherein a phase shift is induced at one frequ ency owing to the presence of intense light at a different frequency. A Mach-Zehnder waveguide device is proposed to take advantage of this process and has applications for all-optical switching and demultiplex ing, potentially at power levels near 10 W by using quasi-phase matchi ng in semiconductor waveguides.
