Abstract
A theoretical description is given of the bending loss effect on signal gain in an optical fiber amplifier when Er/sup 3+/-doped fiber is wound on a bobbin. The dependence of signal gain on bending radius for an Er/sup 3+/-doped fiber amplifier pumped by a 1.48- mu m laser diode is determined using the rate equation for a three-level laser system, taking the bending property into account. The fiber parameters necessary to achieve maximum signal gain are shown to be dependent on the bending loss.<>
