Reversible inter-degree-of-freedom optical-coherence conversion via entropy swapping
The entropy associated with an optical field quantifies the field fluctuations and thus its
coherence. Any binary optical degree-of-freedom (DoF)–such as polarization or the field at a …

On the inverse problem of source reconstruction from coherence measurements
We consider an inverse source problem for partially coherent light propagating in the
Fresnel regime. The data are the coherence of the field measured away from the source …
