The Tree of Light as interstellar optical transmitter system
Elisa Bazzani, Anna Valeria Guglielmi, Roberto Corvaja +8
This work aims at investigating the optical transmission system needed for such lightweight sail, taking into account the physical constraints of such unprecedented link and focusi…
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…
Nano-fabrication and characterization of silicon meta-surfaces provided with Pancharatnam-Berry effect
Pietro Capaldo, Alessia Mezzadrelli, Alessandro Pozzato +3
In this paper, the implementation of optical elements in the form of Pancharatnam-Berry optics is considered. With respect to 3D bulk and diffractive optics, acting on the dynamic…
