Long dynamic population gratings (DPGs) formed in rare-earth-doped fibers have unique
spectral characteristics compared to other types of fiber gratings, making them suitable for …

Dynamic population gratings (DPGs) in rare-earth doped fibers are prevalent devices in fiber
lasers for the production of single-longitudinal-mode emission and wavelength self …

Dynamic Bragg gratings can be recorded in rare-earth (eg Er, Yb) doped optical fibres by
two counter-propagating mutually coherent laser waves via local saturation of the fibre …

In this paper, we investigate laser emission at 3.4 μm in heavily-erbium-doped fluoride fibers
using dual-wavelength pumping. To this extent, a monolithic 7 mol% erbium-doped fluoride …

We have studied absorption spectra of optical fibres doped with rare-earth ions (Sm 3+, Tm
3+, Tb 3+, Pr 3+ and Ho 3+) and demonstrated that they are potentially attractive for …

Optoelectronics will undoubtedly playamajor role in the applied sciences of the next century.
This is due to the fact that optoelectronics holds the key to future communication …

Boron-and germanium-doped highly photosensitive cladding is used in a novel design to
achieve photosensitive Er/Yb-doped fibers, permitting short, strong gratings (length≈ 1 cm …

This review paper on erbium-doped fibre laser (EDFL) covers a broad range of designs and
applications related to the field of optical fibre telecommunication. After a brief historical …

For the first time to the authors' knowledge, rare-earth doped fibre and semiconductor lasers
have been passively configured to exploit the available wide gain-bandwidths with flexibility …
