Anisotropic Laser Performance in an Optically Isotropic Crystal by Phonon Engineering
Advanced Photonics Research, EarlyView.The symmetry‐breaking in a photon–phonon collaboratively pumped laser is investigated for the first time. Using an optically isotropic Nd:YAG crystal, the phonon‐assisted electronic transitions accompanied by anisotropic fluorescence emission are observed.

Advanced Photonics Research, EarlyView.An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.

Mimicking Symmetry‐Breaking Einstein Ring by Optical Lens
Advanced Photonics Research, EarlyView.This article uses an optical lens to emulate the gravitational lensing effect and observe the Einstein ring (ER) patterns. The symmetry‐breaking ER, i.e., Einstein cross, is observed utilizing a rotation‐symmetry‐breaking hemi‐ellipsoid lens. Deformed Einstein cross patterns induced by noncollinearly alignment of the light source–lens–observer are ...

Polarization Management on Anisotropic Thin‐Film Lithium Niobate Platform
Advanced Photonics Research, EarlyView.This review focuses on x‐cut thin‐film lithium niobate (TFLN), exploring strategies to mitigate anisotropy and mode hybridization. It covers polarization beam splitters, rotators, splitter‐rotators, polarizers, and polarization‐insensitive components. Key applications include polarization‐division multiplexing, polarization‐insensitive modulation, and ...
