Nanomanagement of dispersion, nonlinearity, and gain of photonic-crystal fibers: qualitative arguments of the Gaussian-mode theory and nonperturbative numerical analysis

摘要

Qualitative arguments of the Gaussian-mode theory and numerical solution of vectorial wave equations are used to demonstrate that arrays of submicrometer air holes can significantly modify the properties of guided modes in optical fibers, enabling a fine tuning of fiber dispersion, nonlinearity, and gain. Fiber dispersion nanomanagement solutions are shown to provide ultraflattened group-velocity dispersion profiles and control the fib6r'nonlinearity and gain. (c) 2006 Optical Society of America.
