Abstract

In the free space optical communication system with
circle polarization shift keying (CPolSK) modulation,
the changes of polarization state of light beam have
significant influence on the system performance. Keeping
the state of polarization (SOP) unchanged on propagation
can reduce the bit error rate. Based on the unified
theory of coherence and polarization, we derive the
sufficient condition for Gaussian Schell-model (GSM)
beam to keep the SOP unchanged. We found that when the
three spectral correlation widths (delta(xx), delta(yy)
and delta(xy)) equal to each other and sigma(x) =
sigma(y), the GSM beam maintains the SOP on propagation.
This conclusion can be helpful for the design of the
transmitter in the CPolSK system.
