Abstract

An oxidatively coloring electrochromic layer of composition M.sub.y CrO.sub.2+x (0.33.ltoreq.y.ltoreq.2.0 and x.ltoreq.2) where M=Li, Na or K with improved transmittance modulation, improved thermal and environmental stability, and improved resistance to degradation in organic liquid and polymeric electrolytes. The M.sub.y CrO.sub.2+x provides complementary optical modulation to cathodically coloring materials in thin-film electrochromic glazings and electrochromic devices employing polymeric Li.sup.+ ion conductors.

Polymer-hybrid electro-optic devices and method of fabricating polymer-hybrid electro-optic devices

Patent Ocola, Leonidas E.; Gosztola, David J.; Yanguas-Gil, Angel

A polymer-hybrid electro-optic device is fabricated by providing a semiconductor substrate, depositing a metal electrode layer on the semiconductor substrate, depositing a dielectric barrier core layer within a gap of the metal electrode layer, patterning a polymer layer to cover the dielectric barrier core layer and partially covering the metal electrode layer, infiltrating the polymer layer with an inorganic component to form a hybrid oxide-polymer layer, and removing excess inorganic component from the semiconductor substrate and metal electrode layer.

Wave-plate structures, power selective optical filter devices, and optical systems using same

Patent Koplow, Jeffrey P [San Ramon, CA]

In an embodiment, an optical filter device includes an input polarizer for selectively transmitting an input signal. The device includes a wave-plate structure positioned to receive the input signal, which includes first and second substantially zero-order, zero-wave plates arranged in series with and oriented at an angle relative to each other. The first and second zero-wave plates are configured to alter a polarization state of the input signal passing in a manner that depends on the power of the input signal. Each zero-wave plate includes an entry and exit wave plate each having a fast axis, with the fast axesmore »« less

Conductive transition metal oxide nanostructured electrochromic material and optical switching devices constructed thereof

Patent Mattox, Tracy M.; Koo, Bonil; Garcia, Guillermo; ...

An electrochromic device includes a nanostructured transition metal oxide bronze layer that includes one or more transition metal oxide and one or more dopant, a solid state electrolyte, and a counter electrode. The nanostructured transition metal oxide bronze selectively modulates transmittance of near-infrared (NIR) spectrum and visible spectrum radiation as a function of an applied voltage to the device.

Graphene photonics for resonator-enhanced electro-optic devices and all-optical interactions

Patent Englund, Dirk R.; Gan, Xuetao

Techniques for coupling light into graphene using a planar photonic crystal having a resonant cavity characterized by a mode volume and a quality factor and at least one graphene layer positioned in proximity to the planar photonic crystal to at least partially overlap with an evanescent field of the resonant cavity. At least one mode of the resonant cavity can couple into the graphene layer via evanescent coupling. The optical properties of the graphene layer can be controlled, and characteristics of the graphene-cavity system can be detected. Coupling light into graphene can include electro-optic modulation of light, photodetection, saturable absorption,more » bistability, and autocorrelation.« less
