US Classification:
257607, 117 2, 257E29105
Abstract:
The present invention provides a photorefractive potassium niobate (KNbO) crystal including a first impurity added substitutionally to the niobium (Nb) site and a second impurity added substitutionally to the potassium (K) site, wherein the first and second impurities are different. There is also provided a method of making the codoped potassium niobate crystal (KNbO) of the present invention wherein the method includes adding at least one of the impurities to a melt composition during crystal growth, adding at least one of the impurities into an existing crystal using thermal diffusion, and/or adding at least one of impurities into an existing crystal using electrically assisted diffusion.

International Classification:
G02F 1/07
US Classification:
359245, 359256
Abstract:
The present invention provides a method for automatically activating an optical light valve. The method includes providing a photorefractive cell having a birefringent medium which is doped with nanoparticles and transmitting light through the photorefractive cell to create an electric field in the photorefractive cell such that the alignment state of the birefringent medium and nanoparticles is changed to thereby reduce the intensity of the light being transmitted therethrough, wherein the intensity of light is reduces without an external power source.

US Classification:
359342, 977932, 977951
Abstract:
The present invention provides a photorefractive hybrid cell including a window and a gain media disposed adjacent the window. The gain media includes nanoparticles therein. The window includes a material that forms a space-charge field. The gain media includes a material having refractive index properties that depend on an electric field. The nanoparticles include a material which responds orientationally to the presence of an electric or a magnetic field.

385 37
Abstract:
The present invention provides a method for adjusting a diffraction grating to changes in ambient conditions. The method includes writing a diffraction grating in the photorefractive waveguide with a laser, measuring spectral characteristics of the diffraction grating, and allowing the diffraction grating to self-write from interference between a forward beam and a Fresnel reflection, such that the diffraction grating is adjusted for changes in ambient conditions.

International Classification:
G02B 27/28 G02B 26/08 G02B 5/30
Abstract:
A universal polarization converter is provided including a polarizer configured to receive unpolarized light. The polarizer is further configured to split the received unpolarized light into a first and second polarized state. At least two quarter wave phase retarders are configured to convert each of the first and second polarized states to opposite handed polarized beams. A cholesteric mirror is configured to combine the opposite handed polarized beams. In other embodiments, the cholesteric mirror may be replaced by a second polarizer and optional quarter wave retardation plate. Further embodiments may include a single polarization converter and multiple quarter wave retardation plates.
