Effects of pattern dependence on high power polarization division multiplexing a

High-power polarization-division-multiplexing (PDM) systems or functional modules, such as self-phasemodulation (SPM)-based all-optical regenerators, cross-phase-modulation (XPM)-based wavelength convertors or format convertors, all-optical logical gate, and so on, may suffer from the effects of pattern dependence. Such effects are experimentally investigated using relative time delay variation between bit sequences with orthogonal polarization states in a 2 £ 10.65 Gb/s high-power on-off keying
