Measurement of bending-induced birefringence in a hollow-core photonic crystal fiber

, 2019
We report the measurement of bending-induced birefringence in the presence of large intrinsic birefringence in a hollow-core photonic crystal fiber (HC-PCF).

Influence of scattering and birefringence on the phase shift between electric field components of polarized light propagated through biological tissues [PDF]

, 2019
The interest to the use of polarized light in various modern biomedical applications is significantly growing. We explore the influence of scattering and birefringence on the phase shift between electric field components of polarized light propagated ...

Synergistic Dual Slip‐Link Toughening of a Water‐Rich Double Network Hydrogel Combining Slide‐Ring and Highly Entangled Networks

Advanced Science, EarlyView.
Two distinct slip‐link mechanisms – the slide‐ring pulley effect and highly entangled chains – are combined in a water‐rich double network hydrogel, achieving synergistic toughening, near‐complete reversibility, and exceptional friction tear resistance at >$>$91 wt.% water.

Zn(C2H4NO2)2(SO2CH3NH2)2 and Zn(C2H4NO2)2[SO2(NH2)2]: Regulation of Unique ZnO(C2H4NO2)2 Units by Polar Tetrahedrons for Balanced UV Nonlinear Optical Performance

Advanced Science, EarlyView.
The modulation of polar tetrahedra enabled the synthesis of an outstanding short‐wave UV NLO crystal, Zn(C2H4NO2)2[SO2(NH2)2], which achieves a rare balance of a large bandgap (5.93 eV), high birefringence (Δn = 0.126 at 546 nm), and strong SHG response (1.36 × KDP), especially achieving excellent phase‐matching throughout the full transparency range ...

Examination of flow birefringence induced by the shear components along the optical axis using a parallel-plate-type rheometer

Scientific Reports
In this study, the concept of rheo-optics was applied to explore the flow birefringence induced by the stress components along the camera’s optical axis since it is often overlooked in the traditional theories of photoelastic flow measurement.
