Abstract
An optical fiber system including an optical fiber and an optical grating is provided. The optical fiber is configured to support M mode groups, where differences in effective refractive index between adjacent mode groups are substantially equal. The optical grating is optically coupled to the optical fiber, and has a period inversely proportional to the difference in effective refractive index between adjacent mode groups. The optical grating is configured to couple all adjacent mode groups in the optical fiber.
