Beginning with a recently formulated unified theory of coherence and polarization for random electromagnetic fields, we show how partially polarized light can be generated through correlation of unpolarized components. The effect is demonstrated by use of a Mach–Zehnder interferometer, showing the possibility of producing light with adjustable spectral density and an adjustable degree of polarization.
