4 OAM × 4 WDM Optical Switching Based on an Innovative Integrated Tunable OAM Multiplexer

A 4OAMx4WDM switching experiment has been carried out combining an innovative integrated tunable OAM multiplexer based on 4-concentric omega-shaped silicon waveguides and a refractive element-based OAM demultiplexer; operation is demonstrated up to 120Gb/s.
