摘要
A large-mode-area single-mode optical fiber based on leaky-mode filtering was prepared by a modified chemical vapor deposition (MCVD) technique. The fiber has a leaky cladding that discriminates the fundamental mode from higher-order modes. A preliminary version has a 25 mu m core diameter and 0.11 numerical aperture. A Gaussian-like mode with 22 mu m mode field diameter was observed after 3 m propagation, in agreement with modeling.
