Abstract
A composite optical fiber including a first optical fiber having a first core with a first diameter being optically fused to a second optical fiber having a second core with a second diameter that is smaller than the first diameter. The first optical fiber has an output end with a tapered end section. The first core tapers down in diameter in the tapered end section from the first diameter and terminates at the output end with a third diameter that is smaller than the first diameter and substantially equal to or smaller than the second diameter. The second fiber has an input end that is optically fused to the output end of the first fiber. The composite optical fiber of the present invention is formed by heating the output end of the first optical fiber, and then pulling the output end of the first optical fiber to form the tapered end section. The output end of the first optical fiber is then optically fused to the input end of the second optical fiber.
