“…One notes that experimental methods applicable in ferroelectrics for the measurement of their spontaneous polarization cannot be employed to determine the spontaneous antipolarization of antiferroelectrics. It has been shown previously [2,3] that the knowledge of quadratic electrooptic coefficients may allow an estimation of the antipolarization. The method applies the relationship between the spontaneous birefringence appearing in the low-temperature antiferroelectric phase with the spontaneous antipolarization, where the spontaneous birefringence is treated as induced by the square of the spontaneous antipolarization.…”

Measurements of the temperature dependence of the quadratic electrooptic coefficient |g 1111 -g 2211 | of ADP were made. The coefficient is found to decrease with an increase in temperature. The results show that the intrinsic quadratic electrooptic coefficient |M 1111 -M 2211 | defined in terms of polarization also dependes on temperature. Employing the temperature dependence of |M 1111 -M 2211 | estimation of antipolarization in lowtemperature antiferroelectric phase of ADP is made.

“…It has been shown that the deviations can affect the depth of modulation at the fundamental frequency and give rise to non-linear distortions of the output signal (see, for example, Refs. [1][2][3][4][8][9][10][11][12][13][14].…”

“…MEASUREMENTS OF THE QUADRATIC ELECTROOPTIC EFFECT Studies of electrooptic properties of crystals are of interest from the point of view both applications and an understanding of the nature of relevant nonlinear susceptibilities. The latter is important because the same nonlinearities are responsible for other nonlinear optical effects (see, for example, Refs 9,[12][13][14][18][19][20][21][22][23]. Furthermore, measurements of quadratic electrooptic coefficients allow to investigate the paraelectric-ferroelectric phase transition in ferroelectric crystals.…”

In this work we report on numerical investigations of the effect of the light beam divergence or imperfect crystal alignment on the response of electrooptic modulators. Resulting nonlinearities are discussed both in terms of nonlinear distorsions of modulators and as related to errors in measurements of quadratic electrooptic coefficients. Our calculations based on the Jones calculus have been performed for uniaxial crystals including KDP, and its isomorphs, and LiNbO 3 . The results obtained confirm that either the response of the modulators or results of electrooptic measurements can be significantly affected by the light divergence or imperfections in the crystals alignment.

Key words fourth-order electrooptic effect, quadratic electrooptic effect, NH 4 H 2 PO 4 , spontaneous antipolarization. PACS 78.20. Jq, 77.84.Fa Applying the relationship between the spontaneous birefringence of ADP appearing in the low-temperature antiferroelectric phase with the spontaneous antipolarization, and taking into consideration the known experimental values for the quadratic and fourth-order electrooptic effects, an estimate is made of the lower limit of the spontaneous antipolarization. The estimation, which employs the fourth-order electrooptic effect, gives the antipolarization P = 1.2·10-2 Cm -2, a value comparable in magnitude to the spontaneous polarization observed in ferroelectrics belonging to the KDP family of crystals.
