Group IV photonics hold great potential for nonlinear applications in the near-and mid-
infrared (IR) wavelength ranges, exhibiting strong nonlinearities in bulk materials, high index …

The aim of this paper is to present an overview of the recent achievements of our group in
the fabrication and optical characterizations of As_2S_3 microstructured optical fibers …

We investigate experimentally and theoretically the nonlinear properties of two distinct
chalcogenide glasses. Nonlinearities are measured through a spatially resolved Mach …

We report the fabrication and characterization of the first guiding chalcogenide As_2S_3
microstructured optical fibers (MOFs) with a suspended core. At 1.55 µm, the measured …

We report a one-laser-shot measurement technique using a phase object at the entry of a 4 f
coherent imaging system to characterize the value of the nonlinear refractive index of …

Broadband supercontinuum (SC) generation requires host material attributes defined by
both optical and physical properties and the material's manufacturability. We review and …

It is known that amorphous chalcogenide materials exhibit unique optical phenomena,
including high nonlinearity, photodarkening, and phase changes. Upon single or repeated …

A simple experimental method is used to obtain the evolution of both the refractive index and
the linear absorption coefficient as a function of the optical wavelength in the near infrared …

Some resolved solid state 77Se NMR spectra are presented in the AsxSe1− x glass family at
ambient temperature. They exhibit three different kinds of Se environments. A comparison …

Nonlinear optics (NLO) and its applications have attracted increasing research interest in
recent years owing to their contribution to the development of photonic technology …
