Effect of Pump Dithering at Each Stage of Cascaded Fiber Optical Parametric Amplifier
Abstract: Cascaded fiber
optical parametric amplifier (FOPA) can enhance gain and bandwidth. The gain and
bandwidth can be further enhanced by dithering the FOPA pump. However, to our
knowledge, theeffects of a pump dithering at every stage of cascaded FOPA have
not been discussed. The study ofperformance at every stage of cascaded FOPA is
quite interesting and beneficial in designing the system.Here, we analyzed,
using OptiSystem software, each stage of a cascaded FOPA, when there was a pumpdithering
and not. The results showed that the pump dithering enhanced the gain and
broaden thebandwidth at every stage. The gain and bandwidth obtained with the
pump dithering were 27 dB and 20nm, respectively. On the other hand, when there
was no pump dithering, the gain and bandwidth were 9 dB and 12 nm,
respectively.
