Abstract :
Summary form only given. Because wavelength exchange (WE) makes use of four-wave mixing (FWM) between two pumps and two signals, the states of polarization (SOP) of pumps and signals strongly affect its operation characteristics. In this paper, we explore the influence of the SOP of pumps and signals in WE, and show that WE with orthogonal pumps gives superior characteristics in terms of extinction ratio, compared to that with parallel pumps. Based on these results, we have also demonstrated polarization-independent WE with orthogonal pumps, by using a polarization-diversity technique. Signal and idler output power variation below 0.4 dB and 0.3 dB has been achieved in this configuration.
