Abstract

Official abstract text for this publication.

Provided is a cladded single crystal sapphire optical fiber. In one embodiment, the innovation provides a method for forming a cladding in a single crystal sapphire optical fiber by reactor irradiation. The reactor irradiation creates ions external to the fiber that enter the fiber, displace atoms in the fiber, and are implanted in the fiber, thus modifying the index of refraction of the fiber near the surface of the fiber and creating a cladding in the sapphire fiber.

First claim

Opening claim text (preview).

What is claimed is: 1. A sapphire optical fiber having an azimuthally uniform internal refractive cladding within the sapphire optical fiber, wherein the sapphire optical fiber is a graded index sapphire optical fiber. 2. The sapphire optical fiber of claim 1 inscribed with at least one type-II Bragg grating. 3. The sapphire optical fiber of claim 1 , wherein the sapphire optical fiber is part of a distributed temperature measurement system. 4. A sensor comprising the sapphire optical fiber of claim 1 . 5. The sensor of claim 4 , wherein the sensor measures temperature. 6. The sensor of claim 4 , wherein the sensor measures strain. 7. The sensor of claim 4 , wherein the sensor measures pressure. 8. The sensor of claim 4 , wherein the sensor measures acceleration.
