“…The observed behavior is expected as reported in the literature [55]- [57]: At low frequencies, BTO's piezo-electric effect causes strain effects (distortions of the lattice) and facilitates a strong EO response. This strong response is reported to decay over two resonances, the first at ∼100 MHz, the second -a soft phonon resonance [56] -at ∼25 GHz.…”

Integrated ferroelectric plasmonic modulators featuring large bandwidths, broad optical operation range, resilience to high temperature and ultracompact footprint are introduced. Measurements show a modulation bandwidth of 70 GHz and a temperature stability up to 250°C. Mach-Zehnder interferometer modulators with 10-µm-long phase shifters were operated at 116 Gbit/s PAM-4 and 72 Gbit/s NRZ. Wide and open eye diagrams with extinction ratios beyond 15 dB were found. The fast and robust devices are apt to an employment in industrial environments.

“…From these results, it is evident that, like in KNbO 3 [18], the ionic components are major contributors to EO coefficients and electronic components are not much significant in tetragonal BaTiO 3 . This result is supported by the earlier theoretical study [2] on BaTiO 3 .…”

“…A few studies towards understanding the origin of their EO coefficients were reported in literature. Recent theoretical study [2] suggested the importance of ionic contribution to its EO properties. The ionic polarization associated with relaxation process occurring at higher frequency (of about 200 MHz) is suggested to be responsible for larger value of r 42 coefficient.…”

Linear optical susceptibility and clamped linear electro-optical tensor coefficients of tetragonal BaTiO 3 are calculated using a formalism based on bond charge theory. Calculated values are in close agreement with experimental data. The covalent Ti-O bonds constituting distorted TiO 6 octahedral groups are found to be major contributors to the electro-optic coefficients making them more sensitive than the BaO 12 groups for these properties. Orientations of chemical bonds play an important role in determining these properties.

“…In the following, we try to qualitatively explain the dramatic behavior of the EO coefficients as a function of C Mg . A frame model for the EO coefficient of LN can be established on the basis of the general one for an inorganic crystal: the EO coefficient of LN includes three possible contributions, i.e., the piezo‐optic, ionic, and electronic ones. Among them, the ionic contribution plays a predominant role in the doping effect on the EO coefficient of LN, and the EO properties of LN originate from the deformation and polarizability of NbO 6 and LiO 6 clusters.…”

A series of Mg2+/Er3+‐codoped congruent LiNbO3 crystals were grown by Czochralski method from the growth melts containing 0.5 mol% Er2O3 while varied MgO content from 0.0 to 7.0 mol%. The unclamped electro‐optic coefficients γ13 and γ33 of these crystals were measured by Mach–Zehnder interferometry. Two different voltage‐applying schemes were adopted: one is the DC voltage applied to the crystal via Al films coated onto crystal surfaces and another is via a pair of external Cu slab electrodes. The coefficients measured by the two schemes show similar strong dependence on Mg2+ concentration. The dependence is non‐monotonous, dramatic, and unusual, and reveals the features of two Mg2+ concentration thresholds of optical damage: one in the Mg2+ concentration range of 1.2–2.0 mol% (in crystal) and another in 4.5–5.0 mol%. Around the threshold the electro‐optic coefficient decreases abruptly at first and then recovers quickly, and the coefficient drops by >20% (12%) at the first (second) threshold, which exceeds the error 3% considerably. The dramatic behavior is qualitatively explained on the basis of the EO coefficient model of LiNbO3 and the defect structure model for Mg2+‐doped LiNbO3.
