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

We present experimental results on post-tuning the dispersion of a two-dimensional
photonic crystal waveguide made from Ge_33As_12Se_55 chalcogenide glass by …

Due to the large scientific and technical interest in the mid-infrared (MIR) spectral region,
and the limitations of MIR light sources, we focus on the generation of a broad …

Photo-darkening and photo-bleaching are well known phenomena in As-Se and Ge-Se
chalcogenide glasses, respectively. Consequently, a systematic dependence of photo …

Quest for photo-stable amorphous thin films in ternary Ge_xAs_ySe_100-xy chalcogenide
system is reported. Studied layers were fabricated using pulsed laser deposition technique …

Maximal optical nonlinearity obtainable in amorphous materials at telecommunication
wavelengths of∼ 1.5 μm is predicted. Applying a semiconductor concept, we suggest that …

We discuss the influence of photoinduced effects (PIEs) on the measurements of nonlinear
refractive indices and nonlinear absorption coefficients. A chalcogenide glass film Te 20 As …

High carrier mobility and a direct semiconducting band gap are two key properties of
materials for electronic device applications. Using first-principles calculations, we predict two …

In this paper, we report the variations in linear and nonlinear refractive indices of Ge 20 Ga 5
Sb 10 S 65, Ge 20 Ga 5 Sb 10 Se 65, Ge 25 Sb 10 S 65 and, Ge 16 As 24 S 60 …

The Mach-Zehnder interferometer (MZI) is a common structure for integrated all-optical
switches. We proposed and designed an all-optical 2× 2 switch that is based on the MZI …
