Multimode Fiber Bragg Grating Wavelength Filter in a 10-Gb/s System

A 10-Gb/s transmission experiment has been performed on multishell multimode fiber Bragg gratings. The device can simultaneously serve as wavelength filter and mode selector and is compatible with conventional graded refractive index multimode fiber (MMF) components. This could be a promising technology for wavelength-division multiplexing and mode diversity in practical MMF-based optical access networks.
