“…24,25 As a consequence, only a few laboratories were able to demonstrate the spectral broadening up to this limit in the mid-IR. 11,[26][27][28] As a side note, rare earth-doped glasses used for emission around 2 µm are also sensitive to OH content, which is responsible for the quenching of photoluminescence. 29 The glass structure is modified by OH impurities, which lead to non-bridging oxygens, similar to alkali-containing glasses, and result in a decrease in network formation as well as a decrease of the transformation range viscosity and glass transition temperature.…”

We reviewed the tellurite glass purification studies performed over the last 20 years, in particular dealing with the mid-infrared transmission performances. Best results are obtained under rich O 2 atmosphere with platinum crucibles although Gibbs energy calculations show that other crucibles material are possible such as gold or alumina. From the point of view of the thermodynamics of involved oxidation reactions only, we identified the suitable conditions based on Gibbs energy calculations to be a synthesis temperature set above 900K and a O 2 pressure around 10 5 Pa. The performances of the different purification technics were also compared. Finally, we analyzed the tellurite fibers recently optimized for mid-infrared which present low attenuation up to 4 µm allowing supercontinuum generation up to 5 µm.

“…Meanwhile, if width inner core is 3.0µm, the ZDW will shift to higher wavelength. At this inner core size, there is found that the ZDW may obtain in outer core range of 1.0-1.5 µm which deals with lowest attenuation window for silica fiber around 1.55µm [6,7]. For inner core 2.0µm, the ZDW is only slight changes arround 1.44µm.…”

“…inner and outer core, and inner and outer cladding. We investigate a role of width of inner and outer core in order zero dispersion width (ZDW) occurs around 1.55 µm, wavelength of the lowest attenuation in silica fiber [6,7]. This fiber is proposed for SMF application in long distance fiber communication.…”

Fiber optics have become a vital role in telecommunication technologies with many benefits, i.g. high speed transmission, non-electromagnetic interference and low energy consumption. An excellent single mode fiber (SMF) must provide a low attenuation and dispersion which occurs at same wavelength, i.e. 1550 nm. But, in silica based SMF, this property cannot be achieved in a bulk form. Meanwhile, the direct experiment is really not the best choice. Therefore, a simulation fiber design take a crucial role into account for obtaining zero dispersion shift. We design SMF geometry with zero dispersion by resizing the width of core and cladding. This design consists of inner and outer core-clad profile. We also provide several width boundaries for matching the lowest dispersion to the lowest attenuation in silica fiber-based. Moreover, the results shows that dispersion property of the design is suitable for long-haul optical communication systems.

“…Zero dispersion analysis is obtained by tracing the dispersion line over wavelength. The initial value of the lowest dispersion of silcon fiber is 1.3μm [6,7]. Wavelength range is from 1.3μm until 1.7μm in 5000 steps.…”

“…FO network is high speed transfer, immunity to electromagnetic interference, and non corrosive materials [3][4][5]. Meanwhile, power losses and dispersion are still problematic issue in developing SMF for higher frequencies [6,7]. Optimization of design is a better step and important part in fiber manufacturing in order to suppress the cost of fabrication and its maintenances [4,[8][9][10][11][12].…”
