Dual Multiplexing of Wavelength and Orbital Angular Momentum for Expanded Information Capacity With a Single Freeform Micro‐Structured Element

ABSTRACT Optical multiplexing is an important method for expanding information capacity. Here, we propose and experimentally demonstrate dual multiplexing of wavelength and orbital angular momentum (OAM) for expanded information capacity with a single freeform micro‐structured el...
