A single crystal of lithium niobate is an important optoelectronic material. It can be grown
from direct melt only in a lithium deficient non-stoichiometric form as its stoichiometric …

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 …

Point intrinsic and extrinsic defects, especially paramagnetic ions of transition metals and
rare-earth elements, have essential influence on properties of lithium niobate, LN and …

Photorefractive damage, optical absorption, photoconductivities, and photogalvanic currents
of stoichiometric LiNbO_3 single crystals with different Mg do** levels have been …

We present a detailed characterization of photorefraction in on-chip high-Q lithium niobate
(LN) microresonators. We show that the photorefractive effect in these devices exhibits very …

Stoichiometric LiTaO3 single crystals, 45mm in diameter and 50–85mm in length, were
grown by the double crucible Czochralski method equipped with automatic powder supply …

Usage of lithium niobate in nonlinear optics is seriously hampered by optical damage, in
particular, where high intensity is needed. Do** with magnesium can improve its …

We have investigated microscale to nanoscale ferroelectric domain and surface engineering
of a near-stoichiometric LiNbO 3 crystal by using scanning force microscopy. The single …

Undoped and MgO-doped LiNbO3 single crystals with near-stoichiometric compositions
were grown from K2O-doped melts and Li-rich melts by two different growth techniques …

We explored a number of factors affecting the properties relevant to holographic optical data
storage by using a two-color recording scheme in reduced, near-stoichiometric lithium …
