Title: Innovations of Roger Stolen in Optical Fiber Technology

Introduction

Roger Stolen is a notable inventor based in Gallatin, TN (US), recognized for his contributions to optical fiber technology. He holds a total of four patents, showcasing his innovative approach to enhancing fiber optics.

Latest Patents

One of his latest patents is titled "Holey optical fiber with random pattern of holes and method for making same." This invention involves creating a random array of holes in an optical fiber through gas generated during the fiber drawing process. The gas forms bubbles that are drawn into long, microscopic holes. The gas is produced by a gas-generating material such as silicon nitride, which oxidizes to produce nitrogen oxides when heated. Alternatively, silicon carbide or other nitrides or carbides can be used as the gas-generating material. The random holes can provide cladding for optical confinement when located around a fiber core, and they can also be present in the fiber core itself. The fibers can be made of silica, and these random hole fibers are particularly useful as pressure sensors, as they experience a significant wavelength-dependent increase in optical loss when pressure or force is applied.
