    Abstract: An optical modulator is disclosed. The modulator (10) is based upon an ARROW waveguide, consisting of a substrate (12), a lower cladding (16), an interference layer (18), and a core layer (20). An electronic element (14) is formed in the structure to control the free-carrier concentration in the interference layer (18). The light is coupled by gratings (22,24) into the interference layer (18), where the free-carrier concentration is controlled by the element (14), which in turn controls the modulation of the light in the interference layer (18) before it is coupled back to the core (20) layer.

    Abstract: A device for the changing of the wavelength of light comprising a non-linear optical crystal, first and second optical waveguides that are formed in the non-linear optical crystal, and an introducing means that is positioned adjacent to the second optical waveguide, the light being incident upon the first optical waveguide and propagated within the first optical waveguide, resulting in harmonic light that satisfies the phase-matching conditions, and the harmonic light being introduced, by the introducing means, into the second optical waveguide from which the harmonic light is output.
