TLDR
In this article, the first demonstration of Bragg reflector grating filters in Ti: LiNbO3 single-mode channel guides was reported, achieving TE polarisation in Y-cut (X-propagating) material.Abstract:
The first demonstration of Bragg reflector grating filters in Ti: LiNbO3 single-mode channel guides is reported. Filter bandwidths as narrow as 0.14 nm centred at 1.476 μm have been achieved for TE polarisation in Y-cut (X-propagating) material.read more

Optical solitons due to quadratic nonlinearities: from basic physics to futuristic applications
TL;DR: In this paper, the authors present an overview of nonlinear phenomena related to optical quadratic solitons, i.e., intrinsically multicomponent localized states of light, which can exist in media without inversion symmetry at the molecular level.

A narrow-band interference filter with photorefractive LiNbO3
TL;DR: In this paper, a narrowbandwidth interference filter was developed using volume holography in photorefractive LiNbO3 crystals, which works as a Bragg reflector using a volume hologram recorded, fixed and developed in a Li NbO 3 sample.

Diffracting device having distributed bragg reflector and wavelength changing device having optical waveguide with periodically inverted-polarization layers
TL;DR: A diffracting device consists of a substrate made of LiTaO 3, an optical waveguide extending in a central upper side of the substrate for transmitting 860 nm wavelength coherent light radiated from a semiconductor laser, a plurality of gratings periodically arranged on the optical waveguarantee at regular intervals, and a covering layer arranged on both the gratings and the optical beamguide as mentioned in this paper.
