The physical basis of the domain engineering in ferroelectrics and its application to lithium
niobate crystals were reviewed. The unified kinetic approach to the domain structure …

In this paper the most important properties of lithium niobate crystals for photonic
applications are reviewed. We will summarize how acting on the stoichiometry, sample …

We show here conclusively that the internal field originates from nonstoichiometric point
defects in LiNbO 3 crystals. The switching fields required for 180° domain reversal in …

This paper reviews the quasi‐phase‐matched (QPM) waveguide nonlinear‐optic device
technologies for generation of quantum‐entangled twin photons indispensable for quantum …

A systematic study of the kinetics of 180° domains as a function of external electric field is

potential use in optical measurement systems, high-density optical storage, and biomedical …

Frequency doubling of a 684 nm laser diode in a first-order periodically poled LiTaO 3 is
presented. Controlling the side growth of the domain inverted region during high-voltage …

We report studies of second-harmonic generation (SHG) of femtosecond pulses in long
periodically poled lithium niobate waveguides under large conversion conditions. Strong …

Dominant factors influencing domain broadening in periodically poled ferroelectric domain
structures for quasi-phase-matched nonlinear optical converters are studied. It is shown that …
