High-precision point-by-point fiber Bragg grating inscription

open access: yesResults in Physics, 2021
The paper presents a novel multi-pass point-by-point method for high-precision inscription of fiber Bragg gratings with a femtosecond laser radiation. The dynamics of the gratings formation is demonstrated in comparison with the classical method of UV ...

Polarisation-independent Bragg gratings in ion-exchanged glass channel waveguides [PDF]

open access: yes, 2000
The polarisation dependence of Bragg gratings photowritten in ion-exchanged glass waveguides is characterised for waveguides with different mask-opening widths and burial depths.

Nonlinear Magneto-Optical Bragg Gratings

open access: yesPhysical Review Letters, 2006
In magneto-optical gratings the magnetic dipolar coupling superimposed on the electric dipolar one introduces nonreciprocity and spectral discrimination between circular polarization states, measured by a Zeeman-like splitting of the photonic Bragg resonances.

Hyperspectral study of the coupling between trions in WSe$_2$ monolayers to a circular Bragg grating cavity

open access: yesComptes Rendus. Physique, 2021
Circular Bragg gratings compose a very appealing photonic platform and nanophotonic interface for the controlled light-matter coupling of emitters in nanomaterials.

A simple method for fabricating phase-shifted fibre Bragg gratings with flexible choice of centre wavelength [PDF]

open access: yes, 2009
A simple technique for fabricating phase-shifted fibre Bragg gratings (PSFBGs) without the use of a phase-shifted phase mask is presented. Two, 3-mm long, standard fibre Bragg gratings (FBGs) were inscribed sequentially in singlemode fibre at the same

Bragg grating rogue wave [PDF]

open access: yes, 2015
We derive the rogue wave solution of the classical massive Thirring model, that describes nonlinear optical pulse propagation in Bragg gratings. Combining electromagnetically induced transparency with Bragg scattering four-wave mixing, may lead to ...

Phase modulation technique for high modulation wide band planar Bragg grating fabrication [PDF]

open access: yes, 2013
Direct UV Grating Writing (DGW) is effective route for fabricating high quality Bragg gratings, similar to fiber Bragg gratings, in a planar geometry. We will present a phase modulation controlled DGW method using an Electro-Optical Modulator for planar ...

Fiber Bragg Grating Based Thermometry [PDF]

open access: yesNCSLI Measure, 2015
In recent years there has been considerable interest in developing photonic temperature sensors such as the Fiber Bragg gratings (FBG) as an alternative to resistance thermometry. In this study we examine the thermal response of FBGs over the temperature range of 233 K to 393 K.

Fabrication of tunable chirped mPOF Bragg gratings using a uniform phase mask.

open access: yesOptics Express, 2018
We demonstrate chirped Bragg gratings fabrication in doped microstructured tapered polymer fibers by using a uniform phase mask. The use of high photosensitive benzyl dimethyl ketal (BDK) doped core fiber allows to obtain chirped Bragg gratings by means ...
