Slow-light optical bullets in arrays of nonlinear Bragg-grating waveguides [PDF]
, 2006 We demonstrate how to control independently both spatial and temporal dynamics of slow light. We reveal that specially designed nonlinear waveguide arrays with phase-shifted Bragg gratings demonstrate the frequency-independent spatial diffraction near ...

Recording of the Multiplexed Bragg Diffraction Gratings for Waveguides Using Phase Mask
Photonics, 2020 The paper describes a stable method for multiplexed recording of the Bragg diffraction gratings for waveguides using a phase mask. Diffraction waveguides in this experiment were made of photo-thermo-refractive glass.

Bounded modes to the rescue of optical transmission [PDF]
, 2007 This paper presents a brief survey of the evolution of knowledge about diffraction gratings. After recalling some basic facts, historically and physically, we introduce the concept of Wood anomalies.

Diffraction of complex molecules by structures made of light [PDF]
, 2001 We demonstrate that structures made of light can be used to coherently control the motion of complex molecules. In particular, we show diffraction of the fullerenes C60 and C70 at a thin grating based on a standing light wave.
