Experimental Demonstration of a Dynamic 10 G bit/s WDM Header/Label Recognition Structure

All-Optical QPSK Pattern Recognition in High-Speed Optoelectronic Firewalls

“…To process optical packets on the fly, Martinez et al [17] proposed a novel recognition scheme using SOA-based Mach-Zehnder interferometer (SOA-MZI) to implement cascaded XOR logic gates for 2-bit pattern recognition from 10Gbps optical labels. Aljada et al [18] even used a reconfigurable dedicated Opto-VLSI processor to recognize 4-, 6-and 8bit patterns in dynamic 10Gbps WDM headers/labels. For higher processing speed during the pattern recognition, a simplified Vander Lugt correlator [19] implemented by a 20km single-mode fiber, a Phase Modulator (PM), and a dispersioncompensation module was proposed and demonstrated to recognize a 4-bit pattern from 100Gbps optical packet headers and the design could be scaled up for 8-bit headers recognition at 1Tbps as the authors claimed.…”

Automatic multirate all-optical routed network based on optical code division multiplexing solution

“…One of the most promising issues is all-optical label recognition modules. Indeed, packet-switched architectures using label recognition modules have been proposed including time and wavelength domain labels [5]- [6], amplitude-shift-keying (ASK) labels [7], frequency-shift-keying (FSK) labels [8], and subcarrier modulated-labels (SCM) [9]. Employing optical-code-division multiple access (OCDMA) to code labels is another approach and could be used in multiple-access networks, in which multiple simultaneous users share the transmission media [10].…”
