Locked entropy in partially coherent optical fields

M Harling, VA Kelkar, KC Toussaint Jr, AF Abouraddy - Physical Review A, 2024 - APS
We introduce a taxonomy for partially coherent optical fields spanning multiple degrees of
freedom (DOF) based on the rank of the associated coherence matrix (the number of …

Isoentropic partially coherent optical fields that cannot be interconverted unitarily

M Harling, VA Kelkar, KC Toussaint Jr, AF Abouraddy - Physical Review A, 2024 - APS
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 that can …

Measurement of coherence-polarization matrix from a single-frame recording

S Chandra, RK Singh - Optics and Lasers in Engineering, 2025 - Elsevier
Abstract Characterization of statistical properties of a vector source requires fast and efficient
