International Classification:

H01L 29/38
H01L 21/00

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.

Assignee:

The Unites States of America as represented by the Secretary of the Air Force - Washington DC

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.

International Classification:

H01S 5/00

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.

Assignee:

United States of America as represented by the Secretary of the Air Force - Washington DC

International Classification:

G02B 6/34

US Classification:

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.
