“…The different fabrication parameters of modified chemical vapor deposition (MCVD) coupled with solution doping (SD) was optimized to achieve a preform with moderately uniform dopant distribution along with the fiber core. 7,18 Zr-EDF used in this study has the cutoff wavelength of 1075 nm and a numerical aperture (NA) of 0.17. 16,17 The erbium-doping along the Zr-EDF is uniform since other fiber section of Zr-EDF also provides the same performances.…”

“…Two pump laser diodes operating at 980 nm were used to pump Zr-EDF in forward and backward directions to provide high gain and high output power with a relatively flattened gain spectrum. In the previous studies, 7,[16][17][18][19] several different lengths of heavily doped Zr-EDFs between 0.5 and 4 m have been characterized regarding their spectral gain and NF performances.…”

“…As an alternative promising rare earth doped fiber type to the recent results is Zirconia-Yttria-Alumino co-doped Erbium-doped fiber(Zr-EDF) and therefore, it was investigated as an active gain medium in doped fiber amplifiers in detail. 7,[16][17][18] Zr-EDF can easily be spliced with SMF due to the similarity in melting temperature. Also, Zr-EDF amplifier (Zr-EDFA) can be heavily doped with erbium and has a very high pump conversion efficiency requiring a shorter active fiber length for amplification in L-band when it is compared with a conventional L-EDFA.…”

In this study, gain clamping performance in an L-band zirconium-erbium co-doped fiber amplifier (Zr-EDFA) with a very short length of heavily doped fiber and FBG based lasing control structure was presented. A simple gain clamping design based on a symmetrical narrow band C-band fiber Bragg grating (FBG) pair addition was used in the L-band Zr-EDFA with bidirectionally pumping scheme. An L-band gain of higher than 25 dB was obtained with a maximum noise figure (NF) of 5 dB in the conventional Zr-EDFA design which was higher than the previous results obtained with forward pumping scheme. When a couple of narrow band FBGs at Bragg reflection wavelength of 1542 nm are used as the lasing mechanism for gain clamping in L-band operation, small signal gain of Zr-EDFA decreases, but on the other hand, the gain is clamped at almost 15.5 dB with a flattened gain spectrum along a dynamic range of 25 dB for the signal input powers between À30 and À5 dBm with the expense of 1.5 dB NF penalty.

“…Dielectric materials were initially used in telecommunication as base materials for the fabrication of radio frequency and microwave components such as tunable filters, amplifiers and oscillators [1][2][3][4]. Later, these materials were used as dielectric resonators for radio waves in antennas, opening up an important field in telecommunications [5].…”

Development and Characterization of Titanium Dioxide Ceramic Substrates with High Dielectric Permittivities

Titanium dioxide substrates have been synthesized by means of solid-state reactions with sintering temperatures varying from 1150 °C up to 1350 °C. X-ray diffraction and scanning electron microscopy (SEM) where employed to investigate the crystal structure, grain size and porosity of the resulting samples. The obtained ceramics are tetragonal (rutile phase) with average grain sizes varying from 2.94 µm up to 5.81 µm. The average grain size of samples increases with increasing temperature, while the porosity decreases. The effect of microstructure on the dielectric properties has been also studied. The reduction of porosity of samples significantly improves the dielectric parameters (relative dielectric permittivity and loss tangent) in comparison to those of commercial substrates, indicating that the obtained ceramic substrates could be useful in the miniaturization of telecommunication devices.

“…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.
