Experimental evidence of Er³⁺ ion reduction in the radiation-induced degradation of erbium-doped silica fibers.

چکیده
The gain of erbium-doped fiber amplifiers is damaged by irradiation partly because of creation of color centers responsible of excess absorption at pump and signal wavelengths. Based on the combination of thermally stimulated luminescence and spectrophotometry, this Letter demonstrates that a part of the gain loss should be associated with the reduction of the density of Er3+ ions by irradiation.

1.2dBkm Gain in an Erbium:Lutecium Co-doped Al/P Silica Fibre
We report a peak gain of 1.2dB/cm at 1535nm in an Erbium:Lutecium codoped Al/P/Si fibre fabricated using a standard MCVD and solution doping technique. This is the highest gain per unit length yet reported in an Erbium doped fiber amplifier. The incorporation of Lutetium into the glass is shown to reduce the erbium ion clustering within the fiber. The highest gain per unit length yet reported f...
متن کاملComposition of nanoparticles in optical fibers by Secondary Ion Mass Spectrometry
The development of new active optical fibre devices requires materials with « augmented » intrinsic properties, though using luminescent ion (LI) –doped silica as host glass. Optical fibers containing Dielectric Nanoparticles (DNP) grown by phase separation are proposed. DNP would optimally fully encapsulate LI to produce « engineered » spectroscopic properties. To determine the composition of ...
متن کاملمدلی برای تعیین توزیع بهینه اربیوم در مغزی فیبرهای نوری اربیومی تقویت کننده به منظور بالا بردن بهره تقویت کنندگی آنها
In this paper, we suggest a novel model, based on input pump power and wave guidestructure, to calculate the Er-density profile in Erbium doped fiber amplifiers. This optimization is carried out for both SMF and DSF fibers. These optimized profiles have a Gaussian-like shape. Using the SMF optimized Er-density profile, high gain enhancement is obtained in a relatively short length of fibers. ...
متن کاملLuminescent Ions in Silica-Based Optical Fibers
We present some of our research activities dedicated to doped silica-based optical fibers, aiming at understanding the spectral properties of luminescent ions, such as rare-earth and transition metal elements. The influence of the local environment on dopants is extensively studied: energy transfer mechanisms between rare-earth ions, control of the valence state of Chromium ions, effect of the ...
متن کاملMo-pecvd (metal-organic Plasma Enhanced Chemical Vapour Deposition) of Erbium-doped Hydrogenated and Deuterated Amorphous Carbon
Erbium (Er) ion has been widely used in silica fiber-based active photonic devices, given its characteristic emission around 1.5 μm. Hydrogenated and deuterated amorphous carbon (a-C:H and a-C:D, respectively), thin film materials offering tailorable opto-electronic properties, have not been explored thoroughly as host materials for Er. The objective of this research is to study the potential s...
