Polarisation-holding in a high-birefringence fibre

Electronics Letters, 1982
The polarisation-holding ability of a 1 km length of high-birefringence fibre is reported. The fibre birefringence increases linearly with frequency and the polarisation-holding parameter h is independent of frequency with a value of 5.5 × 10?6 m?1, indicating average polarisation-holding to ?22 dB.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Low Loss and High Polarization-Maintaining Single-Mode Hollow-Core Anti-Resonant Fibers with S+C+L+U Communication Bands

Photonics
In this paper, a low loss and high polarization-maintaining single-mode hollow-core anti-resonant fiber (PM-HC-ARF) is designed. The elliptical core in the PM-HC-ARF is formed by strategically enlarging selected cladding air holes along the y-axis ...

Highly Birefringent, Low-Loss, and Near-Zero Flat Dispersion ENZ Based THz Photonic Crystal Fibers

IEEE Photonics Journal, 2020
In this paper, we present and compare two experimentally feasible photonic crystal fiber (PCF) designs ($\textit{Type-I}$ and $\textit{Type-II}$) which ensure near-zero flattened dispersion with ultra-high phase and group birefringence at THz frequencies.

ACOUSTIC BIREFRINGENCE AT ELECTROMAGNETIC EXCITATION OF SOUND IN IRON BORATE CRYSTALS [PDF]

Радиофизика и электроника, 2016
High temperature antiferromagnets such as iron borate, hematite etc., have high magnetoelastic coupling. As a result, in the conditions of birefringence effect, there is a possibility to control parameters of sound waves by a small external magnetic ...

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

Advanced Materials, EarlyView.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Mitigation of the birefringence dispersion on the polarization coupling measurement in a long-distance high-birefringence fiber [PDF]

, 2012
Due to the birefringence dispersion, the polarization coupling parameter measurement in high-birefringence fiber decreases obviously with the fiber length, especially for long-distance fibers.
