Abstract
Methods and devices to split electromagnetic waves across broad bandwidths in correspondence with orbital angular momentum states combined with orthogonal polarization states are disclosed. The described methods can be used in fiber communication and imaging systems. The devices include three-dimensional (3D) scattering structures that can be using existing CMOS processes and direct write lithography techniques. Performance metrics based on the intensity and contrast of the split electromagnetic waves are also disclosed.
