Numerical Analysis of an Yb3+:Er3+:Tm3+:Ho3+ Wideband Optical Fiber Amplifier [PDF]

EPJ Web of Conferences
In this work, we numerically investigate the gain properties of an Yb3+:Er3+:Tm3+:Ho3+ co-doped optical fiber amplifier. The numerical simulations show that a gain higher than 15 dB in a wavelength range of 300 nm can be achieved. The erbium amplifies in

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

Advanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Broadband silica-based thulium doped fiber amplifier employing dual-wavelength pumping

, 2016
We report a broadband and gain-flattened silica-based thulium-doped fiber amplifier with dual-wavelength pumping (790nm + 1600nm). 15dB gain bandwidth is more than 220nm ranging from 1700 to 1920nm with a maximum gain of 29dB and a noise figure of less ...

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

Advanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

Wideband Spectrum-Sliced ASE Source Operating at 1900-nm Region Based on a Double-Clad Ytterbium-Sensitized Thulium-Doped Fiber

IEEE Photonics Journal, 2012
A wideband spectrum-sliced amplified spontaneous emission (ASE) source operating in 1900-nm region is demonstrated using a newly developed double-clad ytterbium-sensitized thulium-doped fiber (YTF) and a Sagnac loop mirror.

Linearly polarized, Q-switched Er-doped fiber laser based on reduced graphene oxide saturable absorber

, 2012
We demonstrate generation of linearly polarized pulses from a passively Q-switched Erbium-doped fiber laser. The cavity was designed using only polarization maintaining (PM) fibers and components, resulting in linearly polarized output beam with degree ...
