Title: Pierre Guerder: Innovator in Coated Monocrystalline Products and Optical Waveguides
Introduction
Pierre Guerder is a notable inventor based in Pithiviers, France. He has made significant contributions to the field of materials science, particularly in the development of coated monocrystalline products and optical waveguides. With a total of 4 patents to his name, Guerder's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
Guerder's latest patents include a method for forming coated monocrystalline products. This method involves a polydiacetylene coating layer deposited upon an organic microcrystal. The coating is characterized by a large, uniform surface area that is monoriented and free of cracks. The preferred embodiment utilizes a layer of [1,6-di-n(carbazolyl)-2,4-hexadiyne] deposited by epitaxy onto an acid orthophthalate monocrystal of an alkali metal, ammonium, or thallium. The process includes cleaving the acid orthophthalate monocrystal along its (001) plane, depositing a diacetylenic monomer onto the cleaved face of the crystal by heat evaporation under vacuum conditions, and polymerizing the monomer upon the crystal face. The coated layer can be removed from the crystalline substrate by applying a composition such as carbon or an acrylic polymer to form a backing and separating the resultant monoriented film from the crystal by partially immersing the coated crystal in water.
Another significant patent is for an optical waveguide with a fluorine-doped core. This optical waveguide exhibits only slight attenuation over both the visible and near-infrared range. The waveguide comprises an optical fiber whose core is made up of a fluorine-doped silica glass, possibly including an oxide that increases the index of refraction of the silica.
