Infrared (IR) fibers offer a versatile approach to guiding and manipulating light in the IR
spectrum, which is becoming increasingly more prominent in a variety of scientific …

Mid‐infrared materials antireflection is in high demand for high‐powered or ultra‐broadband
coherent light sources, where conventional antireflection coatings cannot be reliably …

Photonic technologies offer numerous functionalities that can be used to realize
astrophotonic instruments. The most spectacular example to date is the ESO Gravity …

Revolver optical fibers (RF) are special type of hollow-core optical fibers with negative
curvature of the core-cladding boundary and with cladding that is formed by a one ring layer …

A review of the current progress in fiber optics for the mid-infrared range of the spectrum (2.0–
50.0 µm) is performed. The problem in development of infrared (IR) optical fibers with the …

We demonstrate an all-fiber wavelength conversion system from the C-band to the
wavelength range of 2.30–2.64 µm of the mid-infrared (MIR). A series of nonlinear …

Optical fibers on the base of especially pure Ge 20 Se 80 and Ga 10 Ge 15 Te 73 I 2 glasses
are prepared and applied as the material of sensing elements. To connect the sensing …

Recent results of research of passive and active optical waveguides made of high-purity
chalcogenide glasses for middle infrared fiberoptic evanescent wave spectroscopy of liquid …

A Yb femtosecond laser was used to fabricate antireflective microstructures on CdSSe single
crystal samples. We investigated several microstructure fabrication methods, including direct …

Using the Michelson technique we measured the refractive indices for the plane-parallel thin
plates made of AgCl_1− xBr_x (0≤ x≤ 1) and, to the best of our knowledge, for the first time …
