Optical communications through highly scattering channels using the coherence-rank
Mitchell Harling, Chandler Stevenson, Ayman F. Abouraddy +1
In optical communications, logical bits are encoded in physical degrees-of-freedom (DoFs) of the electromagnetic field. Consequently, optical scattering in a communications channel…

Iso-entropy partially coherent optical fields that cannot be inter-converted unitarily
Mitchell Harling, Varun A. Kelkar, Kimani C. Toussaint +1
For partially coherent optical fields in which a single binary degree of freedom (DoF) is relevant, such as polarization, entropy uniquely identifies the class of optical fields th…

Locked entropy in partially coherent fields
Mitchell Harling, Varun A. Kelkar, Kimani C. Toussaint +1
We introduce a taxonomy for partially coherent optical fields spanning multiple degrees of freedom (DoFs) based on the rank of the associated coherence matrix (the number of non-ze…
