"PHORBITECH is a European project funded under the FET-Open Programme within the 7FP Programme involving 6 European and 1 extra-European partners. PHORBITECH is working on the development of an optical toolbox of highly innovative optical components and devices for the full control of orbital angular momentum, including its generation, manipulation, transmission and detection. The results will have future applications in quantum information technology, high density optical data storage, and materials probing. orbital angular momentum (OAM) is a degree of freedom of light associated with rotationally structured transverse spatial modes of light beams, as in helical wave-front beams. in many respects, oam is analogous to polarization, but in contrast to polarization it is defined in an unbounded infinite-dimensional space."
