“…The selection of suitable glass host for fabricating erbium doped fiber (EDF) is an essential requirement for higher optical amplification efficiency. Over the past several years, extensive research has been carried out on the incorporation of Er in various glass host materials such as silica, alumina, telluride, phosphate, chalcogenide, bismuthate, and fluorozirconate, lithium niobate, lanthanum glasses, etc . in order to make fiber amplifier covering C‐band (1525–1565 nm) and L‐band (1565–1610 nm) with low noise, low loss, and compatibility with fiber lightwave systems.…”

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.

“…For achieving the fluorescence enhancement as high as possible, different host materials other than pure silica, for example, doped silica, phosphate glasses, telluride glasses, fluoride glasses, bismuth-based glasses doped with Er ions have been investigated. [2][3][4][5][6] These different host materials have shown their own advantages (wider emission, higher Er doping level, etc. ), but considering the practical applications in present telecommunication systems, silica-based glass still has cutting edge over the other host materials due to its low loss, ruggedness, compatibility with other system components, and low manufacturing cost.…”

International audienceThe fabrication of Er-doped ZrO2-based nanocrystalline phase-separated silica optical preforms by the MCVD and solution doping techniques is presented. Fabricated preform cores are nearly transparent and contain phase-separated rare-earth doped nanocrystalline particles with diameters mainly in a range from 20 to 80 nm. High concentrations of erbium and aluminium in preform cores of about 0.3 and 14 mol%, respectively have been achieved without defects on the core-cladding interface. Spectral losses in a range 800-1600 nm and fluorescence spectra of erbium ions around 1550 nm measured on a fibre drawn from the preform are reported

“…This has spurred the development of compact fiber amplifiers with a very short gain medium length [3][4][5][6][7]. To compensate for the short gain medium length, the active fiber needs to be doped with so much higher erbium ion concentration.…”

In this paper, we demonstrate a wideband Bismuthbased erbium doped fiber amplifier (Bi-EDFA) using two pieces of bismuth-based erbium-doped fiber (Bi-EDF) with a total length of 67 cm as gain media in a double pass parallel configuration. Both Bi-EDFs have an erbium ion concentration of 6300 ppm. Compared to conventional silica-based erbiumdoped fiber amplifier (Si-EDFA) with the same amount of erbium ions, the Bi-EDFA provides a higher attainable gain as well as a greater amplification bandwidth, which ranging from 1525 to 1620 nm. The proposed Bi-EDFA achieved a wideband gain of around 18 dB within the wavelength region from 1530 to 1565 nm. The noise figures are maintained below 10 dB within a wide wavelength region from 1535 nm to 1620 nm.Gain, dB
