Field-Programmable Topological Torons in Chiral Nematic Liquid Crystals
Adithya Pradeep, Urban Mur, Ji Qin +7
Torons are three-dimensional double-twist solitons in chiral nematic liquid crystals that form localised director configurations protected by topology and bounded by closed defect…
Tunable Dynamic Speckle Generation for Random Illumination Microscopy
Lilian Magermans, Assia Benachir, Nathan P. Spiller +7
Speckled illumination enhances widefield fluorescence microscopy by enabling optical sectioning and super resolution. In random illumination microscopy, sequences of speckled illum…
Multiplexed vector beam conversion via complex structured matter
Runchen Zhang, Tade Marozsak, An Aloysius Wang +9
Structured light, in which the amplitude, phase, and polarization of an optical field are deliberately tailored in space and time, has enabled unprecedented control over optical fi…
Full vectorial field sensing using liquid crystal droplet arrays
Xuke Qiu, Jinge Guo, Jiahe Cui +8
Determining the amplitude, phase, and polarization profile of light is essential for both fundamental scientific discovery and applications spanning optical metrology, microscopy,…
Speckle suppression in digital in-line holographic microscopy through liquid crystal dynamic scattering
Emilia Wdowiak, Nathan Spiller, Tianxin Wang +7
We demonstrate speckle noise reduction in an in-line holographic imaging system using a Zwitterion-doped liquid crystal dynamic scatterer (LCDS) cell diffuser. Integrated into a mi…
Inkjet Printed Liquid Crystal Droplet for Complex Beam Manipulation
Mengmeng Li, Chao He, Steve J. Elston +6
The inkjet-fabricated liquid crystal (LC) droplet device not only capitalizes on the intrinsic birefringence properties of liquid crystals but also leverages the hemispherical shap…
