“…20,21 Pr 3+ doped Y 2 SiO 5 was investigated for electromagnetically induced transparency. 22 Despite its wide use in visible spectral range optical applications a rather incomplete knowledge seems to exist about its accurate long-wavelength optical properties. For example, a complete set of the transverse optical (TO) and longitudinal optical (LO) phonon mode frequencies, amplitudes, and eigendielectric displacement vectors has not been determined, neither by theory nor by experiment.…”

We determine the frequency dependence of the four independent Cartesian tensor elements of the dielectric function for monoclinic symmetry Y2SiO5 using generalized spectroscopic ellipsometry from 40-1200 cm −1 . Three different crystal cuts, each perpendicular to a principle axis, are investigated. We apply our recently described augmentation of lattice anharmonicity onto the eigendielectric displacement vector summation approach [A. Mock et al., Phys. Rev. B 95, 165202 (2017)], and we present and demonstrate the application of an eigendielectric displacement loss vector summation approach with anharmonic broadening. We obtain excellent match between all measured and model calculated dielectric function tensor elements and all dielectric loss function tensor elements. We obtain 23 Au and 22 Bu symmetry long wavelength active transverse and longitudinal optical mode parameters including their eigenvector orientation within the monoclinic lattice. We perform density functional theory calculations and obtain 23 Au symmetry and 22 Bu transverse and longitudinal optical mode parameters and their orientation within the monoclincic lattice. We compare our results from ellipsometry and density functional theory and find excellent agreement. We also determine the static and above reststrahlen spectral range dielectric tensor values and find a recently derived generalization of the Lyddane-Sachs-Teller relation for polar phonons in monoclinic symmetry materials satisfied [M. Schubert, Phys. Rev. Lett. 117, 215502 (2016)].

“…Coherent quantum interactions between light fields and matters, such as the EIT effect, are usually accompanied by light-induced refractive index changes and absorption changes [9,111], which can be employed to actively adjust the polarization state of light under appropriate conditions. For example, through the use of quantum coherence in the Rb atomic vapor, Wielandy et al [112] showed that an initially isotropic atomic vapor could be modified to behave as a linearly or circularly birefringent material, which could be employed to control the polarization state of light through another controlling beam, while, through the asymmetry of the EIT effect in a multilevel system in an Rb atomic ensemble, Wang et al [113] demonstrated coherently controllable rotation of light polarization with a large tuning range.…”

“…We studied the EIT-induced birefringence and achieved a controllable polarization rotator at the EIT point in Pr:YSO crystal [111]. Two parameters, the orientation angle ϕ and the ellipticity ε, were employed to describe the polarization state of light.…”

We reviewed the recent progress in coherent manipulation on light fields based on the electromagnetically-induced transparency (EIT) effect in Pr3+-doped Y2SiO5 crystal. The results show that, on one hand, the atomic coherence grating, formed when the light pulse is stored in Pr3+:Y2SiO5 crystal under the EIT condition has similar properties to the traditional holographic grating. On the other hand, the atomic coherence grating has its own unique characteristics that are different from those of traditional holographic grating. The EIT-induced nonlinearity and atomic coherence gratings can be used to manipulate the amplitude, the phase and the polarization state of light fields; therefore, they are of important applications for optical signal processing, quantum information processing and imaging processing.
