Undergraduate experiment with fractal diffraction gratings [PDF]
, 2011 We present a simple diffraction experiment with fractal gratings based on the triadic Cantor set. Diffraction by fractals is proposed as a motivating strategy for students of optics in the potential applications of optical processing.

Optical Manipulation of Whispering Gallery Mode Microlasers for Controlled Cellular Delivery
Advanced Optical Materials, EarlyView.Optically trapped whispering‑gallery microlasers are precisely positioned onto non‐phagocytic mammalian cells to report local refractive‑index changes in real time. Time‑dependent wavelength shifts reveal successive stages from membrane contact to internalization.

Red‐Sensitive Photopolymerizable Glass for Fabrication of Holographic Optical Elements
Advanced Optical Materials, EarlyView.This study presents a novel photopolymerizable glass capable of optical patterning using red‐wavelength laser exposure. Red‐light sensitivity was achieved through the incorporation of a photoinitiating system composed of methylene blue (MB) and N‐phenylglycine (NPG).

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 ...
