    Abstract: The invention relates to an optical system for opto-optical information processing, which can be used in the field of integrated optics, especially for light-controlled switching, branching light and regenerating optical signals in communications networks. The aim of the invention is to provide a means of processing optical signals simply and flexibly. The inventive optical system uses a waveguide array in which the individual waveguides are coupled evanescently. At least one signal beam of a known wavelength is coupled into the waveguide array at an angle which prevents the signal beam from being diffracted when passing through said waveguide array, with at least one control beam of a known wavelength. The signal beam and the control beam cross inside the waveguide array, so an influence can be exerted.

    Abstract: Electro-optic modulators are disclosed. An electro-optic modulator comprises an electro-optic polymer layer, semiconductor layers, ferroelectric material layers, and electrodes. The semiconductor layers are positioned on each surface of the electro-optic polymer layer. The refractive index of the semiconductor layers in the optical and RF domains is higher than the refractive index of the electro-optic polymer layer in the optical and RF domains. The ferroelectric material layers are positioned on each semiconductor layer opposite the electro-optic polymer layer. The refractive index of the ferroelectric material layers in the RF domain is higher than the refractive indices of both the electro-optic polymer layer and the semiconductor layers in the RF domain. The refractive index of the ferroelectric material layers in the optical domain is lower than the refractive index of the semiconductor layer in the optical domain. The electrodes are positioned on each ferroelectric material layer opposite the semiconductor layer.

    Abstract: The present invention is related to a method to control the nucleation and to achieve designed domain inversion in single-domain ferroelectric substrates (e.g. MgO doped LiNbO 3 substrates). It includes the first poling of the substrate with defined electrode patterns based on the corona discharge method to form shallow domain inversion (i.e. nucleation) under the electrode patterns, and is followed by the second crystal poling based on the electrostatic method to realize deep uniform domain inversion. Another objective of the present invention is to provide methods to achieve broadband light sources using a nonlinear crystal with a periodically domain inverted structure.

    Abstract: The instability of the mean wavelength of a superfluorescent fiber source (SFS) is reduced by randomizing the polarization of light from a pump source or by using polarization maintaining components. In one embodiment, the polarization of a pump source is made more random, leading to greater stability of the mean wavelength of the SFS, with an output mean wavelength that is stable to better than 3 ppm for full rotation of the pump polarization state. In another embodiment, the polarization of optical radiation throughout the device is kept substantially constant by using polarization maintaining fiber and components, thereby leading to enhanced mean wavelength stability of the SFS.
