Fast reconfigurable SOA-based all-optical wavelength conversion of QPSK data employing switching tunable pump lasers

We demonstrate a dynamically reconfigurable SOA-based all-optical wavelength convertor for QPSK data at 12.5 GBuad using a fast switching tunable laser as one of the pump sources. The experimental results indicate that it is feasible to build fast reconfigurable wavelength convertors with <;30 ns switching time.
