Latest Patents
Raychaudhuri's latest patents include a method of applying hermetic coating on optical fiber. This invention involves providing an optical fiber, freshly drawn from an optical preform, with two external hermetic coatings. The primary coating is a metallic or dielectric coating achieved through a heterogeneous nucleation thermochemical deposition (HNTD) technique. This technique allows the fiber to pass through a reaction zone containing a gaseous medium with reactants that decompose or chemically react at a predetermined temperature. This temperature is derived from the heat retained at the fiber surface during the fiber forming process, eliminating the need for additional heating. The secondary coating is deposited using either HNTD or a chemical vapor deposition process, followed by an additional polymer coating layer.
Another patent focuses on the hermetic coating for an optical fiber, which also involves two external coatings. The primary coating is again a metallic coating applied using the HNTD technique. The secondary coating is formed by immersing the fiber in a deposition bath containing a liquid medium with reactants capable of deposition onto the primary coating. This process can be achieved by applying a current or by using reactants that deposit at predetermined temperatures without current. The resulting fiber is then enhanced with an additional polymer coating layer.
