Control monitoring of routing bits and data packets in WDM networks using wavelength-to-time mapping

We demonstrate a wavelength-to-time technique for control monitoring in a wavelength-division multiplexing (WDM) network. We recover the routing header bits across parallel wavelength as well as determine the existence of data packets for switching purposes. We show results for a routing-bit monitor of multiple channels with the speed of 2.5 Gbps and a packet/frame monitor for multiple channels with the speed of 100 MHz.
