Here, via novel design of an optical fiber device referred to as a photonic lantern, where the radial mode index ("m") is neglected, for the first time we demonstrate the simultaneous generation and multiplexing  ...  While canonical methods of OAM mode generation are effective, a method that can simultaneously generate and multiplex OAM modes with low loss and over broad spectral range is still in great demand.  ...  The slight variations between the calculated and measured modes are a product of the small geometry deformation of the final fabricated core at the multimode end of the OAM photonic lantern.  ...

Máté Farkas, Nayda Guerrero, Jaime Cariñe, Gustavo Cañas, Gustavo Lima
2020 arXiv   pre-print
Since MUBs lie at the core of several quantum information protocols, our results are of practical interest for future quantum works relying on space-division multiplexing optical fibers.  ...  Due to the high-overlap of the interferometer's optical modes achieved with this technology, we are able to reach the required visibilities for self-testing the implementation of two four-dimensional MUBs  ...  For FMFs, DEMUXs called photonic lanterns are used [46] . For RCFs these devices are called mode sorters.  ...
