Reply to comment on "Observation of subluminal twisted light in vacuum"
Frédéric Bouchard, Robert W. Boyd, Ebrahim Karimi
Recently, we showed experimentally that light carrying orbital angular momentum experiences a slight subluminality under free-space propagation [1]. We thank Saari [2] for pointing…

Optical spin-to-orbital angular momentum conversion in ultra-thin metasurfaces with arbitrary topological charges
Frédéric Bouchard, Israel De Leon, Sebastian A. Schulz +3
Orbital angular momentum associated with the helical phase-front of optical beams provides an unbounded \qo{space} for both classical and quantum communications. Among the differen…
