A Collective Propagation Law of Optical Vortex Constellations and Longitudinal Sensing
Niladri Modak, Rafael F. Barros, Marco Ornigotti +1
Optical vortices are ubiquitous phenomena naturally appearing in wave physics, yet higher-order charges inherently split into constellations of lowest-order singularities at the sm…
Tunable spatio-spectral Target Skyrmions and topological multiplexing
Pedro Ornelas, Niladri Modak, Oussama Korichi +3
Optical Skyrmions have recently garnered much interest providing a potential avenue for high capacity, robust topological information transfer. Typically, Skyrmions are derived fro…
Active control of phase matching in nonlinear metasurfaces using Pancharatnam--Berry phase
Madona Mekhael, Roman Calpe, Tommi K. Hakala +2
Reconfiguring the spectral output of nonlinear metasurfaces after fabrication remains challenging. We address this by exploiting the nonlinear Pancharatnam--Berry phase of …
Volumetric Processing of Structured Light Integrated in Glass
Oussama Korichi, Markus Hiekkamaki, Robert Fickler
Light with complex structures in polarization, phase and amplitude, has attracted a lot of attention in a broad range of applications and fundamental studies in classical and quant…
An epsilon-near-zero-based nonlinear platform for ultrafast re-writable holography
M. Zahirul Alam, Robert Fickler, Yiyu Zhou +3
We re-examine real-time holography for all-optical structuring of light and optical computation using a contemporary material: a subwavelength-thick, spatially unstructured film of…
Multimode interface between optical free-space- and waveguide modes
Teresia Stranden, Oussama Korichi, Matias Eriksson +3
Free-space and on-chip photonic systems are key components in optical communication networks. While free-space beams allow for the flexible generation and manipulation of spatial m…
