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 +5
Microstructured surfaces are central to photonics, biointerfaces, and coating technologies, but they are typically fabricated through multistep workflows involving masks, masters,d…
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…
Reprogrammable holograms from maskless surface photo-morphing
Francesco Reda, Marcella Salvatore, Marco Astarita +2
Holographic technologies have the potentiality to impact our everyday life in many sectors including science, education, entertainment, art, and healthcare. Although holographic sc…
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…
