Degree of polarization and heterodyne spectrum in coherent detection of partially polarized wave fields
Juan Pérez-Téllez, Francisco Javier Mendieta-Jiménez, Arturo Arvizu‐Mondragón · Journal of Modern Optics · 2005
We first study the state of polarization of the superposition of partially polarized, statistically independent optical fields with application in coherent detection systems with emphasis on heterodyne configurations and obtain the DOP of the mixture of wave fields. Next we obtain the available heterodyne power after photodetection. Finally we obtain the spectrum of the photocurrent process resulting from the coherent detection of partially polarized amplitude-stabilized fields.
