Halogen Bond Unlocks Ultra‐High Birefringence

Angewandte Chemie International Edition
AbstractAnisotropy is crucial for birefringence (Δn) in optical materials, but optimizing it remains a formidable challenge (Δn >0.3). Supramolecular frameworks incorporating π‐conjugated components are promising for achieving enhanced birefringence because of their structural diversity and inherent anisotropy. Herein, we first synthesized (C6H6NO2)+

Double Sb-N Coordination Enables Record-High Birefringence in UV-Transparent Crystals.

Angewandte Chemie - International Edition
Achieving high birefringence in ultraviolet (UV)-transparent crystals has remained a significant challenge due to the absence of systematic design methodologies.

High-Performance Sulfate Optical Materials Exhibiting Giant Second Harmonic Generation and Large Birefringence.

Angewandte Chemie - International Edition, 2022
Discovering novel sulfate optical materials with strong second-harmonic generation (SHG) and large birefringence is confronted with a great challenge attributed to the intrinsically weak polarizability and optical anisotropy of tetrahedral SO4 groups ...

Dodecagonal photonic quasi-crystal fiber with high birefringence

Journal of the Optical Society of America A, 2016
A photonic quasi-crystal fiber (PQF) with high birefringence is proposed. A dodecagonal Stampfli quasi-periodic lattice of air holes constitutes the cladding of the PQF. The PQF maintains the properties of high birefringence and single-mode operation regime in a wide wavelength range from 1.2 to 2.0 μm by optimizing the size of the air holes around the
