Chalcogenide glasses have the advantages of a wide transparency window (over 20 μm)
and high optical nonlinearity (up to a thousand times greater than that of silica glasses) …

Abstract Mid-infrared region (2–20​ μm) is an important region of electromagnetic spectrum.
Most of the molecules including CH 4, CO, NO, NO 2, C 6 H 6, TNT, NH 3, SF 6, HNO 3 …

We reviewed the tellurite glass purification studies performed over the last 20 years, in
particular dealing with the mid‐infrared (mid‐IR) transmission performances. Best results are …

We demonstrate broadband supercontinuum generation over two infrared octaves,
spanning from 1.3 to 5.3 μm, with an output power of 150 mW in robust step-index tellurite …

An overview of the progress on pulse-preserving, coherent, nonlinear fiber-based
supercontinuum generation is presented. The context encompasses various wavelength …

Numerous innovations in photonics have been realized on the basis of nonlinear optical
properties, notably in information technologies. To take advantage of the nonlinear optical …

We present an overview of the fabrication process and characterization of tellurite,
germanate, and germanate–tellurite step-index fibers with different index contrasts. Several …

We present a detailed experimental parameter study on mid-IR supercontinuum generation
in W-type index tellurite fibers, which reveals how the core diameter, pump wavelength, fiber …

Tellurite all-solid hybrid microstructured optical fibers (ASHMOFs) can be used to generate
supercontinua with broad bandwidths in both anomalous and normal dispersion regimes. In …

We report numerical and experimental demonstrations of flexible group-velocity dispersion
regimes in step-index tellurite fibers by fine control of the fiber core diameter. Our simple …
