Tellurite photonic crystal fiber

Abstract

We report the fabrication of a Tellurite photonic crystal fiber, and demonstrate its waveguiding properties. The measured minimum loss is 2.3 dB/m at a wavelength of 1055 nm. The fiber supports several modes, but in practice just the fundamental mode can be used. We have observed strong stimulated Raman scattering in a fiber with an effective area Aeff=21.2microm2, using sub-ns, ~ 1 microJ pump pulses at 1064.

Photonic Crystal Fibers

“…Multicomponent glass offers several useful properties not possessed by silica, such as a high refractive index, good infrared transmittance, high optical nonlinearity and relatively low photon energy. Several fibers made of silicate [8], chalcogenite [9], and tellurite glass [10] have been reported. The silicate glass can be doped much more and therefore the range of possible modifications of their optical and mechanical characteristics is much wider.…”

Thermal and Optical Studies of Rare Earth Doped Tungston–Tellurite Glasses

“…Tellurite glasses are technologically important since they are chemically stable, have high homogeneity and are resistant to divetrification at low temperature [2]. Tellurite oxide (TeO 2 ) used as a host material has several advantages over other oxide glass hosts and the most important one is being its low phonon frequency.TeO 2 glasses are known to be low melting and high refractive index materials, therefore considered to be potential nonlinear materials [3].Their highest refractive indices among oxide glass in the visible and near IR region cause that the TeO 2 based glass systems are the most promising materials in optoelectronic devices [4]. The relatively high refractive index is a consequence of high polarizability of Tellurium ions.…”

Ultrabroad supercontinuum generation in tellurite equiangular spiral photonic crystal fiber

“…Also, the small transmission window of silica glasses (0.2-3 µm) limits the SC generation beyond this range. This limitation has attracted attention towards non -silica glasses such as lead -silicate 3 , fluoride 4 , chalcogenide 5 , and tellurite [6][7][8] glasses that have larger n 2 and some of which are transparent in the mid -infrared window.…”
