Patent number: 11198637Abstract: Gradient refractive index (GRIN) materials can include multi-phase composites having substances with differing refractive indices disposed non-uniformly within one another. Particular glass composites having a gradient index of refraction can include: an amorphous phase, and a phase-separated region disposed non-uniformly within the amorphous phase. The glass composites include a mixture containing: GeZ2 and A2Z3 in a combined molar ratio of about 60% to about 95%, and CsX and PbZ in a combined molar ratio of about 5% to about 40%, where A is As, Sb or Ga, X is Cl, Br or I, and Z is S or Se. When A is As, the glass composites include PbZ in a molar ratio of about 15% or less. The amorphous phase and the phase-separated region have refractive indices that differ from one another. More particularly, A is Ga or As, X is Cl, and Z is Se.Type: GrantFiled: May 14, 2018Date of Patent: December 14, 2021Assignees: Lockheed Martin Corporation, University of Central Florida Research Foundation, Inc.Inventors: Clara Rivero Baleine, Kathleen Richardson, Charmayne Smith

Patent number: 10437083Abstract: A mask array apparatus includes a monolithic structure that includes a substrate layer transmissive for at least a portion of an infrared wavelength band and an array of individually addressed pixel structures. Each pixel structure is in stacked relation above or below the substrate layer, and includes at least one micro-plate heating element layer, circuitry, and at least one phase change material (PCM) element. The heating element layer is transmissive for the wavelength band, and has switchable on and off states configured to produce temperature changes. The circuitry is configured to individually address the heating element layer, separately from heating element layers in other pixel structures, to switch the heating element layer between the on and off states. The PCM is in stacked relation above or below the heating element layer and configured to change transmissive states in the wavelength band in response to the temperature changes.Type: GrantFiled: October 20, 2014Date of Patent: October 8, 2019Assignees: Lockheed Martin Corporation, The Penn State Research FoundationInventors: Clara Rivero Baleine, Theresa S.

Patent number: 10132965Abstract: A refractive index device and method of making it include obtaining a glass structure comprising a plurality of nucleation sites. The glass structure is formed from a glass composition that comprises a first chemical component and a second chemical component. A crystal of the second chemical component has a different second refractive index from a first refractive index of the first chemical component. Each nucleation site defines where a crystal of the second chemical component can be grown. The method includes causing crystals of the second chemical component to grow in situ at a set of the plurality of nucleation sites in order to produce a spatial gradient of a refractive index in the glass structure.Type: GrantFiled: April 22, 2016Date of Patent: November 20, 2018Assignees: Lockheed Martin Corporation, The Penn State Research Foundation, Clemson University Research FoundationInventors: Clara Rivero Baleine, Theresa S.

Patent number: 9908808Abstract: Ternary chalcogenide glass materials containing germanium can display enhanced properties compared to corresponding binary chalcogenide glass materials lacking germanium. For instance, ternary chalcogenide glass materials containing germanium, arsenic and selenium can exhibit improved Vickers micro-hardness values and other enhanced mechanical properties while still maintaining small changes in refractive index as function of temperature. Such ternary glass materials can have a formula of (AsySez)[(100-x)·0.01]Gex, in which x ranges between about 1 and 5, y ranges between about 30 and 40, z ranges between about 60 and 70, and y+z=100. Methods for producing the ternary glass materials can include blending arsenic, selenium, and germanium as a melt, and cooling the melt to form the ternary glass material.Type: GrantFiled: August 18, 2016Date of Patent: March 6, 2018Assignees: Lockheed Martin Corporation, University of Central Florida Research Foundation, Inc.Inventors: Clara Rivero Baleine, Benn H.
