Abstract: A method for producing nanostructured, hydrophilic, transmissive, anti-reflective surfaces is described. The method for providing a hydrophilic surface includes steps of providing a substrate that is transmissive in at least one wavelength in the infrared to ultraviolet range of the electromagnetic spectrum and comprises at least one surface including nanostructures of a size smaller than the at least one wavelength; and functionalizing the at least one surface with hydroxyl groups thereon. This method provides devices having excellent transmittance and anti-reflectance properties and which are resistant to seawater.

Abstract: This application relates generally to polymer materials comprising nanoscale ceramic particles for use as a coating in clad pump fiber lasers, including those that function at eye-safer wavelengths and the related method of making them. Fluorinated polymers that possess low refractive index, low optical loss, and high thermal stability are combined with fluorinated ceramic nanoparticles that possess low refractive index and high thermal conductivity to develop a polymer material.

Abstract: The present invention provides a method for synthesizing a new class of inorganic-organic polymeric materials. These polymers are made with a backbone comprising chalcogenide elements such as sulfur, selenium, and/or tellurium along with organic crosslinking moieties that determine its physical and optical properties. Also disclosed are the related polymeric materials. These polymers are suitable for optical applications in short wave infrared (SWIR, 1-3 ?m) and mid wave infrared (MWIR, 3-8 ?m) regions.

Abstract: Methods for producing nanostructured, hydrophobic, superhydrophobic, or hydrophilic, transmissive, anti-reflective surfaces are described. The method for providing a hydrophilic surface includes steps of providing a substrate that is transmissive at at least one wavelength in the infrared to ultraviolet range of the electromagnetic spectrum and comprises at least one surface including nanostructures of a size smaller than the at least one wavelength; and functionalizing the at least one surface with hydroxyl groups thereon. A hydrophobic or superhydrophobic surface can be provided by contacting the at least one surface with a hydrophobic fluoropolymer for a time sufficient to apply at least a monolayer of fluorine-containing material to the at least one surface. These methods provide devices having excellent transmittance and anti-reflectance properties and which are resistant to seawater.
