“…This is consistent with Wang's model for the linear electro-optic coefficients for lithium niobate (LiNbO 3 ). 11 As stated above, Wang's model does not apply to LiTaO 3 because n o Ͻ n e . Using the value that Wang calculated for r 33 to obtain the necessary constants in the theoretical equation for the electro-optic coefficients, one may obtain the wavelength dependence of r 33 of LiNbO 3 , which is shown in Fig.…”

“…[6][7][8][9][10] For other wavelengths, the only other published result is for a clamped crystal at 3.39 m. 9 Wang has developed a model to predict the electro-optic coefficients of ferroelectric materials. 11 However, in as much as the index of refraction along the extraordinary axis is greater than that along the ordinary axis, the model is not applicable to LiTaO 3 . Previous experimental methods included interferometry and reflection, 6,12-14 but none has been used with LiTaO 3 .…”

Electro-optic coefficients of lithium tantalate at near-infrared wavelengths

et al. 2004

The unclamped linear electro-optic coefficients r 13 and r 33 for lithium tantalate are known at only one wavelength, 632.8 nm, whereas the clamped coefficients are also known at 3.39 m. In the unclamped mode the effects of mechanical changes caused by piezoelectric and elasto-optic effects are accounted for in the electrooptic coefficient. We demonstrate a novel technique that uses a ferroelectric domain micropatterned electrooptic deflector to measure the unclamped linear electro-optic coefficients r 13 and r 33 at any wavelength. Using this method, we have determined these values for lithium tantalate at 980, 1330, and 1558 nm.

Second Harmonic Generation induced by the electric field of a strong nearly single-cycle terahertz pulse with the peak amplitude of 300 kV/cm is studied in a classical inorganic ferroelectric thin film of (Ba0.8Sr0.2)TiO3. The dependences of the SHG intensity on the polarization of the incoming light is revealed and interpreted in terms of electric polarization induced in the plane of the film. As the THz pulse pumps the medium in the range of phononic excitations, the induced polarization is explained as a dynamical change of the ferrolectric order parameter. It is estimated that under action of the THz pulse the ferroelectric order parameter acquires an in-plane component up to 6% of the net polarization.

Numerical Study of Reconfigurable Mid‐IR Single Photon Sources Based on Functional Ferroelectrics

et al. 2020

The future of quantum photonic technology depends on the realization of efficient sources of single photons, the ideal carriers of quantum information. Parametric downconversion (PDC) is a promising route to create highly coherent, spectrally pure single photons for quantum photonics using versatile group velocity matching (GVM) and tailored nonlinearities. However, the functionality to actively control the poling period of nonlinear crystals used in PDC is currently missing, yet would enable to dynamically modify the wavelength of single photons produced in the PDC process. Herein, a detailed GVM study is presented for functional PMN‐0.38PT material which can be dynamically repolled at ambient conditions with fields as low as 0.4 kV mm−1. The study reveals phase‐matching conditions for spectrally pure single photon creation at 5–6 µm. Further, a practical approach is proposed for on‐flight wavelength switching of the created single photons. The reported reconfigurable functionality benefits a wide range of emerging quantum‐enhanced applications in the mid‐IR spectral region where the choice of single photon sources is currently limited.
