Abstract
The present disclosure provides an optical fiber and a method of fabricating an optical fiber. The method includes providing an optical fiber, the optical fiber defining a length having a proximal end and a distal end. The optical fiber includes a first core profile zone defining a first core diameter, and a second core profile zone defining a second core diameter different from the first core diameter. The optical fiber includes a first transition zone connecting the first core profile zone to the second core profile zone. The first core profile zone, the second core profile zone, and the first transition zone are formed as a single, continuous fiber.
