Soft Mesocrystal Enabled Multi‐Degree Light Modulation (Laser Photonics Rev. 18(5)/2024)

Soft Mesocrystal Enabled Multi‐Degree Light Modulation Multi‐degree light modulation is realized based on the mapping relationship between optical degrees of freedom (the spin, wavelength, and geometric phase of light) and hierarchical structures of blue‐phase mesocrystals (the chirality of helix, cubic lattice constant, and the azimuthal orientation of lattices). The work by Yanqing Lu, Wei Hu, and co‐workers (see article number 2301283) provides a promising strategy for fantastic large‐scale parallel and multi‐degree light modulations.
