Electrically tunable helicity of cholesteric heliconical superstructure [Invited]
Conglong Yuan, Wenbin Huang, Xiaoqian Wang, Dong Shen, and Zhigang Zheng
The dynamic manipulation of the helicity in a cholesteric helical superstructure could enable precise control over its physical and chemical properties, thus opening numerous possibilities for exploring multifunctional devices. When cholesteric material satisfies the sufficiently small bending elastic effect, an electrically induced deformation named the cholesteric heliconical superstructure is formed. Through theoretical and numerical analysis, we systematically studied the tunable helicity of the heliconical superstructure, including the evolution of the corresponding oblique angle and pitch length. To further confirm the optical properties, Berreman’s 4 × 4 matrix method was employed to numerically analyze the corresponding structure reflection under the dual stimuli of chirality and electric field.

Holographically fabricated, highly reflective nanoporous polymeric distributed Bragg reflectors with red, green, and blue colors [Invited]

We report holographic fabrication of nanoporous distributed Bragg reflector (DBR) films with periodic nanoscale porosity via a single-prism conuration. The nanoporous DBR films result from the phase separation in a material recipe, which consists of a polymerizable acrylate monomer and nonreactive volatile solvent. By changing the interfering angle of two laser beams, we achieve the nanoporous DBR films with highly reflective red, green, and blue colors. The reflection band of the nanoporous DBR films can be tuned by further filling different liquids into the pores inside the films, resulting in the color change accordingly. Experimental results show that such kinds of nanoporous DBR films could be potentially useful for many applications, such as color filters and refractive index sensors.

Compared with solid materials, soft matters have inherent advantages such as excellent adjustability, high flexibility, scalable size, ease of manufacture, and environmental adaptation. The various interesting properties of soft matter are not only worthy of basic research, but also inspires fantastic applications, especially in photonics. Therefore, this topic focuses on researches about liquid crystal and soft matter photonics. This special issue aims to attract research on soft matter photonics (Soft Mattonics) and promote the development of related applications.
