Abstract
A side pump fiber and a method of making a side pump fiber are provided. A plurality of pump fibers can be joined to a side of a signal fiber, at different locations. The method includes creating a lengthwise, tapered, concave pocket cut in a pump (or side pump) fiber, inserting the signal fiber in the pocket cut, and then coupling the side pump fiber to the center fiber at the pocket cut. Optical amplifiers and lasers, as examples, can be made using the above method and side pump fibers.
