Gain equalization of a six-mode-group ring core multimode EDFA

We propose a 6-mode-group ring core multimode erbium doped fiber amplifier (RC-MMEDFA) capable of providing almost identical gain among the six mode groups within the C band using either core- or cladding-pumped ...

Dual Temperature and Strain Measurement with the Combined Fluorescence Lifetime and Bragg Wavelength Shift Approach in Doped Optical Fiber [PDF]

We have constructed fiber-optic sensors to measure temperature and strain by combining the properties of fiber Bragg gratings with the fluorescent lifetimes of various doped fibers.

Differential modal gain optimization for weakly-coupled few-mode multi-core erbium-doped fiber amplifiers

Optics Express
Space-division multiplexing (SDM) is a key technology to overcome the capacity limit of single-mode fiber systems, using multiple spatial channels in few-mode fibers, multi-core fibers, and few-mode multi-core fibers. Few-mode multi-core erbium-doped fiber amplifiers (FM-MC-EDFAs) can compensate for transmission loss via either core or cladding pumping.

Raman amplification and pulsed lasing in cladding-pumped germanosilicate fiber

We report for the first time Raman amplification in a cladding-pumped fiber. The double-clad germanosilicate fiber was pumped by a Q-switched Er-Yb co-doped fiber laser at 1570 nm. The power conversion efficiency was up to 36%, with a slope of 64%

High-power cladding-pumped Raman and erbium-ytterbium doped fibre sources

, 2007
Raman fibres and rare-earth doped silica fibres have been investigated for many years as gain media for the amplification of optical signals in telecommunications thanks to their broad gain bandwidth. They are now widely used for that application.
