FPGA controlled integrated optical cross-connect module for high port-density optical packet switch

We present an FPGA controlled 4x4 integrated WDM optical cross-connect followed by wavelength converters as optical module for building a large port optical packet switch. Error free operation is obtained for 4 wavelength channels at 40 Gb/s NRZ with 4 dB penalty, switching time of 25 ns and energy consumption of 73.75 pJ/b.
