Large mode area guidance in a simple fiber structure

We demonstrate higher-order-mode (A<sub>eff</sub>~1800μm<sup>2</sup>) propagation in a 100-μm-OD pure-silica fiber with a low-index polymer jacket commonly used for fiber-laser pump-guidance. This simple structure obviates the need for complex designs deemed necessary for realizing large-mode-area fibers.
