Spectral Condensing of All‐Dielectric Structural Colors via Cascaded Formation of Self‐Similar Beams
Advanced Optical Materials, EarlyView.Standalone low‐index microscale ridges (MRs) are promising platforms for all‐dielectric structural color generation. They are compact and easy to fabricate, but their color purity trails behind that of resonator‐ or periodic pattern‐based structural color pixels.

Analysis and Optimization of the Sandwiched Metal-Dielectric Polarizing Beam Splitter Grating
IEEE Photonics Journal, 2016 A reflective sandwiched polarizing beam splitter (PBS) grating with a connecting layer in Littrow mounting is described and designed in this paper. By using two-beam-interference theory for a modal method, a duty cycle and a period of grating can be ...

Nanopatterned Dual‐Carbon‐Dot Photonic Films With Enhanced Light Outcoupling
Advanced Optical Materials, EarlyView.Nanoimprinted dual‐carbon‐dot/PVA films combine composition‐tunable blue–green emission with grating‐mediated directional light outcoupling. Water‐processable B‐CD and G‐CD composites are patterned by drying‐assisted nanoimprinting, producing angle‐selective emission peaks that follow the first‐order diffraction condition and exhibit reference ...

Advanced Optical Materials, EarlyView.A 3D‐printed Terahertz (THz) anisotropic dielectric with programmable permittivity by varying infill density and creating high‐aspect‐ratio channels is presented. The proposed design was evaluated both experimentally, through THz time‐domain spectroscopy, and theoretically, through FDTD simulations and Effective Medium Theory analysis.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics
Advanced Science, EarlyView.The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

New High‐Tc Charge‐Transfer Multiferroicity in the Quasi‐2D Antiferromagnet CrSbS3
Advanced Science, EarlyView.ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...
