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…
Test of mode-division multiplexing and demultiplexing in free-space with diffractive transformation optics
Gianluca Ruffato, Michele Massari, Giuseppe Parisi +1
In recent years, mode-division multiplexing (MDM) has been proposed as a promising solution in order to increase the information capacity of optical networks both in free-space and…
A general theorem on the divergence of vortex beams
G. Vallone, G. Parisi, F. Spinello +3
The propagation and divergence properties of beams carrying orbital angular momentum (OAM) play a crucial role in many applications. Here we present a general study on the divergen…
Experimental near field OAM-based communication with circular patch array
Fabio Spinello, Elettra Mari, Matteo Oldoni +6
A short range experimental communication system, based on Orbital Angular Momentum (OAM) multiplexing, is presented. We characterize circular arrays of patch antennas designed to t…
N-tupling the capacity of each polarization state in radio links by using electromagnetic vorticity
Fabrizio Tamburini, Bo Thidé, Elettra Mari +7
The congestion of the radio frequency bands imposes serious limitations on the capacity and capability of modern wireless information infrastructures. One approach to enable freque…
