“…The fabrication of Er doped nano‐engineered glass based optical fiber based on the incorporation of Al 2 O 3 , Y 2 O 3 , and Sc 2 O 3 into silica glass made to reduce RE clustering compared to pure silica glass along with improving fiber's spectroscopic properties. Insulation of REs ions from matrix vibrations is essential by appropriate material design of the surrounding ion site through the formation of phase‐separated NPs . This involves encapsulation of dopants inside glassy or crystalline NPs, embedded in the fiber glass.…”

“…These silica glass based fibers have several advantages such as high optical transparency, low cost, strong chemical, and mechanical durability. This new technique has attracted a lot of interest as it provide the formation of embedded phase‐separated nanoparticles with crystalline or amorphous nature into RE‐doped SiO 2 host‐matrix to enhance their spectroscopic performance and promises for high‐power optical amplifiers, mode‐locked, and Q‐switched fiber lasers, and broadband SC sources …”

In this work, a new erbium (Er) doped nano‐engineered scandium‐phospho‐yttria‐alumina‐silica (SPYAS) glass‐based optical fiber is reported, fabricated through the MCVD process, and solution doping technique, followed by a suitable thermal annealing of pristine preform. The fabrication process comprises the incorporation of erbium doped phase‐separated scandium‐yttria rich crystalline nanoparticles into the core region through in situ process based on phase‐separation and crystal growth phenomena. The material characterization results, obtained from transmission electron microscopy, electron diffraction pattern, energy dispersive X‐ray, electron probe micro analysis, and X‐ray fluorescence, confirm the formation of Er2O3 doped crystalline phase‐separated scandium‐yttria rich nanoparticles in the core region. The formation of scandium‐ultra rich nano‐crystalline environment, possessing low photon energy around the erbium ions, enhanced the fluorescence intensity. Such kind of nano‐engineered glass reduces the noise figure around 4.35 dB, and provides broadband optical flat gain with an average value of 38.675 dB, varied by less than ±0. 7 dB spanning over a broad wavelength region of 1530–1590 nm compared to the pristine and Sc free Er‐doped fibers. Such kind of nano‐engineered glass based Er doped fiber will be useful for making highly efficient optical amplifiers, suitable for present broadband optical communication systems.

Abstract:We report the results of experimental investigation and theoretical analysis of luminescence decay in Yb/Tm Y-codoped fibers based on nano-modified glass. Based on the experimental results, numerical simulations allowed us to estimate the energy transfer efficiency between Yb 3+ and Tm 3+ ions. It was shown that yttria enhances the Yb/Tm energy transfer making fibers with Y-codoping promising for development of the light sources for laser applications and of up-conversion emitters for visualization applications. These fibers demonstrate energy transfer efficiency of 50 %, which makes them attractive for diode-pumping of Ybions at 975 nm wavelength.

“… in order to tune the spectral properties of RE‐doped preform/fiber and to achieve enhanced RE solubility. Similarly, Yb has been doped into modified silica host glass by various groups where the host glass doped with Al or P is further modified by adding minor quantities of dopants like, Y, La, etc. In this context, Ba has been used as modifier in the fabrication of different silicate glass containing RE ions ; very recently highly BaO‐doped silica glass has been fabricated through molten core method to investigate brillouin spectra of the same and Ba‐doping level in pure silica glass has been determined using MCVD‐solution doping technique .…”

Barium has been established as an alternate codopant other than conventional aluminum or phosphorous for fabrication of rare-earth-(RE) doped optical fiber through modified chemical vapor deposition (MCVD) coupled with solution doping technique. Different optical and material characterization results of our fabricated fibers indicate potential application as amplifier and laser. The amplifier performance of Er-doped fiber and lasing as well as photo darkening (PD) experiment of Yb-doped fiber doped with BaO is presented where Ba serves as an alternate candidate for enhancement of RE solubility in silica glass.
