The Orbital Angular Momentum Encoding System With Radial Indices of Laguerre–Gaussian Beam
Orbital angular momentum (OAM) in optical vortices (OV) beams offers a new dimension of space mode because coaxially propagating OV beams with different azimuthal OAM states are mutually orthogonal.

Optical Orbital Angular Momentum Shift-Keying Communication Using Direct Demodulation
Orbital angular momentum (OAM) shift-keying (SK), which manifests as the rapid switching of OAM modes, is crucial but severely hampered for lacking effective demodulation techniques in OAM communication.

Communication protocols for Free-Space Optical links [PDF]
Táto diplomová práca sa zaoberá správaním protokolu TCP/IP pri prechode bezdrôtovým optickým spojom, ktorý je ovplyvnený atmosférickými turbulenciami. Tie spôsobujú fluktuáciu prijímaného optického výkonu a tým zmenu bitovej chybovosti spoja.
