*gianluca.ruffato@unipd.it

A novel and compact solution is presented to efficiently multiply or divide the orbital angular momentum (OAM) of light beams using a sequence of two phase-elements implementing a properly designed superposition of circular-sector transformations. The experimental tests confirm the capability of the multiplier optics to perform integer multiplication of the input OAM, while the designed dividers are demonstrated to correctly split up the input beam into a complementary set of OAM beams. These elements can find promising applications for the multiplicative generation of higher-order OAM modes, optical information processing based on OAM-beams transmission, and optical routing/switching in telecom.
