Designing interferometers within a single optical beam
Bereneice Sephton, Rakhi Thomas, Carlo Schiano +8
Interferometry provides highly sensitive access to optical phase and is central to much of modern metrology and phase imaging methods. Conventional implementations, however, often…
All-optical Lithography for Spatiotemporal Patterning of High-Modulation Azopolymer Microreliefs
I Komang Januariyasa, Francesco Reda, Nikolai Liubimtsev +4
Microstructured surfaces are central to photonics, biointerfaces, and coating technologies, but they are typically fabricated through multistep workflows involving masks, molds, an…
Stress-driven photo-reconfiguration of surface microstructures via vectorial field-guided lithography
I Komang Januariyasa, Francesco Reda, Nikolai Liubimtsev +7
Pattern formation driven by mechanical stress plays a fundamental role in shaping structural organization in both natural and human-made systems. Using light as a vectorial stimulu…
Electrically tunable liquid-crystal metasurfaces with patterned birefringence and dichroism
Paola Savarese, Sarvesh Bansal, Maria Gorizia Ammendola +7
Light propagation through artificially patterned anisotropic materials, such as dielectric metasurfaces, enables precise control of the spatio-vectorial properties of optical field…
Shapeshifting diffractive optical devices
S. L. Oscurato, F. Reda, M. Salvatore +3
In optical devices like diffraction gratings and Fresnel lenses, light wavefront is engineered through the structuring of device surface morphology, within thicknesses comparable t…
A mid-infrared biaxial hyperbolic van der Waals crystal
Zebo Zheng, Ningsheng Xu, Stefano Luigi Oscurato +10
Hyperbolic media have attracted much attention in the photonics community, thanks to their ability to confine light to arbitrarily small volumes and to their use for super-resoluti…
