Conoscopic interference patterns, channelled spectra and polarimetric techniques have been used for the characterization of pure and doped (with L-arginine amino acid) potassium dihydrogen phosphate (KDP) single crystals. Experimental polarimetric data have been obtained for the frequently used wavelength of 633 nm and for two close wavelengths of 532 and 543 nm in a high-accuracy dual-wavelength polarimeter. The measurement of eigenwave ellipticity in the [100] and [010] directions and between 295 and 340 K shows small differences in the absolute values of the specific optical rotations of KDP crystals doped with L-arginine in the range of 0.7–3.8 wt%. It is found that the gyration tensor component g 11, specific optical rotation and eigenwave ellipticity show different dispersion in the visible spectral region.

“…However, V π is 540 V for PLZT transparent ceramics, 2800 V for LiNbO 3 single crystal, and 8000 V for KDP single crystal. [ 6,8,25 ] The extinction ratio of the transparent ceramics is 13.8, 32.1, 29.3, 32.2, and 34.8 dB as Sm‐doping content increased from 0 to 2 mol%, respectively. Note that the extinction ratio directly affects the sensitivity of the receiver, and a low extinction ratio will easily lead to code element misjudgment and affect the accuracy of information transmission.…”

“…However, the high half-wave voltage (V π ) and easy deliquescent restrict its practical application. [6] LiNbO 3 single crystal, widely used in the field of optical communication, is a benchmark in electro-optic materials. [7,8] However, it has low linear electro-optic (E-O) coefficient of ≈18 × 10 -12 pm V −1 , low damage threshold (<100 MW cm −2 ), and high half-wave voltage V π of 2800 V, making it not applicable in high-power devices.…”

Electro‐optic (E‐O) materials are essential to modern information society, especially for optical switches, modulators, and filters in optical communication. In this paper, ultrahigh transparent (1−x)Pb(Mg1/3Nb2/3)O3‐xPbTiO3 (PMN‐PT) relaxor ferroelectric ceramics are fabricated. The effect of Sm‐doping content (0, 0.5, 1.0, 1.5, and 2.0 mol%) on PMN‐PT transparent ceramics is systematically investigated on the optical transparency, electro‐optic coefficient, extinction ratio, and half‐wave voltage. Results indicate that 0.5 mol% Sm‐doped PMN‐PT ceramic shows the optimal comprehensive performance, including high transparency of 69.6%, large quadratic E‐O coefficient of 35 × 10–16 m2 V−2, decent extinction ratio of 32 dB, and low half‐wave voltage (113 V at d = L = 1 mm). An electro‐optic modulator is designed based on the PMN‐PT transparent ceramics and its application in optical communication is realized, such as rapid information modulation, analog signal (audio frequency), and digital signal (graphic patterns) transmission. These results indicate that Sm‐doped PMN–xPT transparent ceramics are promising candidates for E‐O modulation applications.

“…Therefore, many researchers are devoted to developing different electro-optic (EO) materials, such as LiNbO 3 (LN), KH 2 PO 4 (KDP), lead lanthanum zirconate titanate (PLZT), and Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT). The advantages of LN and KDP single crystals are high optical uniformity, but their low linear EO coefficients (< 20×10 −12 pm•V −1 ) and high half-wave voltages (> 2500 V) limit their wider applications [4][5][6]. The EO property of PLZT is superior to that of LN due to its high quadratic EO coefficient (9×10 −16 m 2 •V −2 ) and relatively low half-wave voltage (< 800 V); however, its significant polarization-dependent scatterings loss and field-induced hysteresis limit its application to high-speed modulation devices [5,7].…”

“…The understanding of the relationship among doping, domain structure, ferroelectric polarization, and EO effect is still limited though tremendous progresses have been made in the preparation of the transparent ferroelectric ceramics and the optimization of their EO effects. Besides, few works have fabricated EO modulation devices based on the PMN-PT ceramics because the preparation of the EO devices is difficult, and it is hard to obtain ultra-high EO coefficients and high light transmittance at the same time [3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Transparent electro-optic (EO) ceramics of La-doped 0.75Pb(Mg 1/3 Nb 2/3 )O 3 -0.25PbTiO 3 (0.75PMN-0.25PT) were prepared successfully. High transparency of 69% in the near-infrared (IR) wavelength (1550 nm) was achieved at 2 mol% La doping, meanwhile it shows an extremely high quadratic EO coefficient of 45.4×10 −16 m 2 •V −2 , which is indispensable for applications in EO devices. The distribution of a polar nanodomain structure of the samples experiences disorder-order-disorder evolution in a La doping range. It is found that a parallelly-stacked polar nanodomain structure with an easier and faster polarization switching in the 2 mol% La-doped sample suggests that an ordering distribution of polar nanoregions would be critical to inducing large EO effect, transparency, and piezoelectric response. A triple-cavity tunable optical filter (TOF) with a single transmission peak and a tuning voltage below 30 V in a tuning range of 190-197 THz was designed based on our ceramics. The work is believed to bridge the relationship among doping-engineering, EO properties, and polarization behavior, which would guide the further optimization of transparent EO ceramics.
