“…Due to the polarization rotation can induce the variety of output power, the polarization rotation combining other non-linearity effect can use in all-optical nonlinear regeneration [9] and all-optical sampling [10] and optical buffer [11] and optical data comparator [12]. Recently, with investigate deeply, the applications of SOA nonlinear polarization rotation at high-speed all-optical signal processing and all-optical logic are more and more widespread along with research deeply [13,14].…”

The phenomena of polarization rotation induced by self-modulation in semiconductor optical amplifier (SOA) are analyzed theoretically. The relationship between polarization parameters and gain as well as phase is obtained by the correlation parameter of ellipse polarization and SOA nonlinearity polarization rotation theory. The experiment employs polarizer drive by walking electromotor and power meter, the light power of 360 degree is measured. The transformation law of output polarization power components is found for obvious polarization rotation in the selected coordinate axes based on connection of polarization state in difference axes. Using this law make the manipulation easily on getting ideal polarization state. It can offer a fine method to realize all-optical switch and other logic elements in experiment. This work is of great significance for the applications of SOA nonlinear polarization rotation at high-speed all-optical signal processing and all-optical logic gate.
