Nonreciprocal waveguide Bragg gratings
Optics Express, 2005 The use of a complex short-period (Bragg) grating which combines matched periodic modulations of refractive index and loss/gain allows asymmetrical mode coupling within a contra-directional waveguide coupler. Such a complex Bragg grating exhibits a different behavior (e.g.

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

Bragg grating rogue wave [PDF]
, 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 ...

Nonlinear Magneto-Optical Bragg Gratings
Physical 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.

Germanium-on-silicon planar concave grating wavelength (de)multiplexers in the mid-infrared [PDF]
, 2013 Mid-infrared wavelength (de)multiplexers based on planar concave gratings (PCGs) fabricated on a germanium-on-silicon waveguide platform are presented. PCGs with two different types of gratings (flat facet and distributed bragg reflectors) are analyzed ...

Fiber Bragg Grating Based Thermometry [PDF]
NCSLI 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.
