Abstract
A waveguide for high efficiency transmission of high energy light useful in ablation procedures at predetermined bandwidths over predetermined distances comprising: an optical fiber core; a silanization agent; layered cladding surrounding the optical fiber core comprising: a first thin metal layer comprising at least two types of metals the first thin metal layer covalently bonded to the core and a second thin metal layer bonded to the second metal layer, and a catalyst component; wherein the silanization agent comprising organofunctional alkoxysilane molecule, such as 3-aminopropyltriethoxysilane (APTS), is a self supporting bridge between the surface of the optical fiber and the first metal layer; the first metal layer is uniformly chemisorbed onto the surface of the optical fiber by means of covalent Si—O—Si bonds with the optical fiber; further wherein the catalyst component derived from an activation solution for enhancing the layered cladding upon the optical fiber.
