Abstract

Cone-shaped profiles illustrate the recently proposed bend-compensated strategy for large-mode-area amplifier fiber design. Simulations show that introducing a bend-compensating gradient into the fiber profile simultaneously improves mode area and reduces higher-order-mode impairments in a spooled-fiber amplifier.
