All-optical switching based on nondegenerate phase shifts from a cascaded second-order nonlinearity
Optics letters, 1993•opg.optica.org
All-optical switching by using a nondegenerate cascaded second-order nonlinearity is
described wherein a phase shift is induced at one frequency 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
demultiplexing, potentially at power levels near 10 W by using quasi-phase matching in
semiconductor waveguides.
