We show through a simple example that fields generated by such sources can possess correlation matrices with interesting properties. In particular, we show that by suitable modulation of the polarization state across the incoherent source, the correlation between the orthogonal components of the field as well as the degree of polarization may drastically change on propagation.engjournal articlehttp://dx.doi.org/10.1364/OL.25.001291http://www.opticsinfobase.orgopen access535BeamsPropagationÓptica (Física)2209.19 Óptica Física
