The design of an all-solid, soft glass-based, large mode area Bragg fiber for effective single
mode operation with mode effective area exceeding 1100 µm^ 2 across the wavelength …

Silica layers fabricated by the sol-gel method are usually amorphous and exhibit a relatively
low refractive index (n∼ 1.46 at about 0.6 μm), high optical transmittances at UV-VIS and …

A spatial optical filter based on a hollow-core silica tube is proposed. Because of the hollow-
core dimensions, it is possible to obtain a periodical spatial filter ranging from 1200 to 1700 …

This paper presents results of preparation and characterization of Bragg fibers with silica
and air cores designed for delivery of laser radiation at 1060 nm. The fibers consist of cores …

The guiding properties of realistic silica/air hollow-core Bragg fibers have been investigated
by calculating the dispersion curves, the confinement loss spectrum, and the field …

This paper presents fundamental characteristics of laboratory designed and fabricated
Bragg fibers with air and silica cores at wavelengths of 632, 975, 1064 and 1550 nm. Fibers …

This paper examines the effect of an intermediate layer between the core and periodic
cladding of a Bragg fibre on its optical properties. It is shown that any TE 0κ mode of a …

The paper presents results on sol–gel preparation and characterization of multilayered
coatings, Bragg mirrors, on silica slides, silica fibers, and inner walls of silica capillaries. In …

Bragg fibers offer new performance for transmission of high laser energies over long
distances. In this paper theoretical modeling, preparation and characterization of Bragg …

In this paper, a scanning cutback method, developed for the investigation of Bragg fibers
waveguide characteristics, is presented. The method relies on fiber excitation by a laser …
