Fabrication of highly nonlinear optical fibers with tellurite glass core and phosphate glass cladding

Spectroscopic properties of highly Nd-doped lead phosphate glass

“…The fluorescence quenching lifetime decreases with increasing Nd 3+ content following the equation [22] ( ) 0 1 f p N Q τ τ = + (10) where is the fluorescence lifetime in the limit Nd → 0, Q is the quenching concentration and p is a phenomenological parameter characterizing the steepness of the fluorescence decays curve. We observe that (open circles) is strongly affected by concentration quenching effect being reduced by ~ 47% when Nd 3+ -doping increases up to10 wt%.…”

“…The low glass melting temperature and the optical fiber development compatibility makes the phosphate glasses suitable candidates for photonic applications [9,10]. The Nd 3+ -doped phosphate glasses are the most common and largest volume of laser glass produced today [11].…”

Broad and ultra-flat optical parametric gain in tellurite hybrid microstructured optical fibers

“…Additionally, tellurite glasses have generated broad interests due to their excellent properties such as corrosion resistance, lowest phonon energy among oxides, high linear and nonlinear refractive indices and high glass stability. The chromatic dispersion profile of tellurite fibers could be tailored and the ZDW could be shifted to telecommunication window by using hybrid microstructured optical fibers (HMOFs) which were proposed and successfully fabricated in our earlier work [3,19].…”

Fabrication and characterization of an all-solid tellurite–phosphate photonic bandgap fiber

“…Recently, great attention has been attached to soft-glass PBGFs due to the broad transparency ranges in the mid-infrared and high nonlinear refractive indices, such as phosphate PBGFs, tellurite PBGFs, tellurite-silica PBGFs, and chalcogenide-silica PBGFs [9,15,[18][19][20][21]. The usage of tellurite and phosphate glasses in fiber fabrication has already been reported [22,23]. However, up to now, the tellurite-phosphate PBGFs are barely touched.…”
