25 February 2008 Measurement of bend-induced nonlinearities in large-mode-area fibers
Author Affiliations +
We present the first direct measurements of enhanced nonlinearities in large-mode-area fibers due to bend induced reductions in effective area. Both Raman scattering and self-phase modulation are observed to increase in tightly coiled fibers. The measured increase in nonlinearity compares well with predictions from simulations of the modal effective area.
