Guo et al, 2023, report that NbOCl2 is a novel thin-material SPDC source. This work presents optical measurements on thick flakes of the material that differ from standard SPDC sources like LiNbO3.

Optical anisotropy of (311) superlattices
Physical Review B, 1994We report a calculation of the electronic properties of GaAs/AlAs (311) superlattices through the Brillouin zone using realistic values of the parameters in a tight-binding Hamiltonian. The nature and the localization of the lowest conduction bands for these low-symmetry structures is investigated and its origin is studied with respect to the layer ...

Optical anisotropy of polypeptide chains
Biopolymers, 1972AbstractOptical anisotropies γ2 of N‐t‐butylacetamide (tBA), N‐Methylacetamide (MA), and N, N‐dimethylacetamide (DMA) have been determined from the Rayleigh ratios for depolarzed scattering by dilute solutions of the amides in p‐dioxane. Traceless optical polarizability tensors \documentclass{article}\pagestyle{empty}\begin{document}$ \widehat{\rm ...

Optical anisotropies in electromodulation
SPIE Proceedings, 1990We describe both reflectance anisotropy and electroreflectance measurements carried out to determine the physical origin of the anisotropies observed in the reflectance spectrum of (001) and (110) GaAs. We find an anisotropy component which depends on impurity concentration for both (001) and (110) surfaces [and on conductivity type for (001) GaAs].

Physica B: Condensed Matter, 1993
Abstract The optical anisotropy of UNi 2 Si 2 has been systematically studied by reflectance spectroscopy in the range of 50 to 37 000 cm -1 . A temperature-dependent absorption peak was found in the c -axis optical conductivity spectra centered at 280 cm -1 in the incommensurate longitudinal spin-density-wave phase (103 K T K ), which, we ...

Optical Anisotropy of Semiconductor Nanowires
2008Semiconductor nanowires are novel nanostructures full of promise for optical applications. Nanowires have subwavelength diameters and large aspect ratios, which combined with the high permittivity of semiconductors lead to a strong optical anisotropy.

Optical anisotropy of biotissues
SPIE Proceedings, 2001To create a model of development of atherosclerosis and other major human diseases the structural and functional peculiarities of bradytrophic tissues were studied in series of investigations. Sclera, cornea, tendon, cartilage and some other tissues belong to bradytrophic tissues, which nutrition is the result of the diffusion of extravasal liquid.

Optical anisotropy of polyisobutene
Polymer, 1976Abstract The distribution of chemical bonds in polyisobutene results in a theoretically zero optical and electrical anisotropy of the polymer according to bond polarizability additivity principles as conventionally applied, irrespective of polymer chain conformation. Non-zero values of the segmental anisotropy (∼4.4 × 10 −40 C 2 m 2 /J) derived from

Optical anisotropy of nanotube suspensions
The Journal of Chemical Physics, 2004A semimacroscopic model of an optically anisotropic nanotube suspension is derived perturbatively from Maxwell’s equations in a dielectric medium. We calculate leading-order expressions, valid in the dilute and semidilute limits, for the intrinsic and form contributions to the complex dielectric tensor in terms of the volume fraction, mean orientation,
