Dispersion-compensating dual-mode optical fibers desirable for erbium-doped-fiber-amplified systems
A broadband dispersion-compensating dual-mode optical fiber with a double-layer profile core is proposed to compensate for positive dispersion in conventional single-mode optical fibers operating near 1.55 {mu}m. This wavelength band is suitable for erbium-doped-fiber-amplified systems. It is known that the first higher-order mode of dual-mode fibers exhibits large negative waveguide dispersion, and double-layer profile core fibers are dispersion-shifted fibers whose transmission and bending losses are lower than those of simple core-cladding dispersion-shifted fibers. Such advantages are attractive for commercial devices or modules. Here, a dispersion-compensating dual-mode fiber with a double-layer profile core that satisfies both low bending loss and broadband dispersion compensation is proposed. {copyright} 2001 Optical Society of America
