Multipole-phase beams: a new paradigm for structured waves
Gianluca Ruffato, Vincenzo Grillo, Filippo Romanato
The control of structured waves has recently opened innovative scenarios in the perspective of radiation propagation and light-matter interaction. In particular, the transmission o…
Non-paraxial design and fabrication of a compact OAM sorter in the telecom infrared
Gianluca Ruffato, Michele Massari, Marcello Girardi +3
A novel optical device is designed and fabricated in order to overcome the limits of the traditional sorter based on log-pol optical transformation for the demultiplexing of optica…
Multiplication and division of the orbital angular momentum of light with diffractive transformation optics
Gianluca Ruffato, Michele Massari, Filippo Romanato
We present a method to efficiently multiply or divide the orbital angular momentum (OAM) of light beams using a sequence of two optical elements. The key-element is represented by…
Total angular momentum sorting in the telecom infrared with silicon Pancharatnam-Berry transformation optics
Gianluca Ruffato, Pietro Capaldo, Michele Massari +2
Parallel sorting of orbital angular momentum (OAM) and polarization has recently acquired paramount importance and interest in a wide range of fields ranging from telecommunication…
Electrically-activated spin-controlled orbital angular momentum multiplexer
Gianluca Ruffato, Etienne Brasselet, Michele Massari +1
We present and test the integration of a static orbital angular momentum mode multiplexer with a dynamical geometric-phase optical element enabling on-demand spin-controlled angula…
Design, fabrication and characterization of Computer Generated Holograms for anti-counterfeiting applications using OAM beams as light decoders
Gianluca Ruffato, Roberto Rossi, Michele Massari +3
In this paper, we present the design, fabrication and optical characterization of computer-generated holograms (CGH) encoding information for light beams carrying orbital angular m…
