Patent number: 7652078Abstract: High concentrations of dye may be prepared in combination with thermoplastic polymers and used in optical polymers as monomeric and dimeric molecular solutions. The method of preparing high concentration levels allows the control over the aggregation of dye molecules that is required to maintain effective nonlinear operation. The present invention is applicable to many systems and is essential to the successful production of working optical limiting devices and other optically transparent polymeric devices, as well as other photonic applications, such as nonlinear optics.Type: GrantFiled: May 9, 2007Date of Patent: January 26, 2010Assignee: George Mason Intellectual Properties, Inc.Inventors: Steven R. Carlo, Eva M. Maya, Arthur W. Snow, Richard G. S. Pong

Patent number: 6994885Abstract: The invention provides an optical filter comprising: a. an organic, solar blind filter dye; and b. a UV-transparent, non-scattering and chemically stable substrate. The substrate may be a UV-transparent nanoporous silica glass solid having pores that are substantially filled with a UV-transparent solvent, which has been selected to dissolve said dye and also to match the refractive index of the nanoporous silica glass solid. Alternatively, the substrate may be a UV-transparent inorganic salt compressed to form a solid body. The invention also provides for methods of making these embodiments and an optical device comprising such an optical filter. The filter provides an efficient solar blind filter that is chemically and dimensionally stable.Type: GrantFiled: November 3, 2004Date of Patent: February 7, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventors: Richard G. S. Pong, Steven R. Flom, James S. Shirk
