چکیده
In the 5G era, more sensitive information will be transmitted on optical networks. Although modern cryptography could support different security mechanisms in layers, layer has not been paid enough attention but it is also vulnerable to attack by tapping or other methods. The optoelectronic firewall one of promising strategies which can accelerate operating speed within manageable costs employing signal processing compared with current electronic firewalls. most significant and challenging component an pattern recognition. However, either latest recognition systems only process OOK BPSK modulation format signals, coherent correlators supporting higher order require advanced components deal a number symbols. this paper, address challenges, we propose, analyze simulate system QPSK signals integrated into all-optical high-speed firewalls used for security. numerical simulation results first demonstrate feasibility, baud rate 100GBaud achieved. Next, threshold-setting method developed proves ability recognize arbitrary target patterns. Then some noise analysis that I branch immune while output power EDFAs Q needs configured carefully. Finally, matched result real Ethernet frame further reveals our proposed promisingly applied

متن کاملAll-optical pattern recognition for digital real-time information processing.
To recognize digital streams of digital data, all-optical and passive techniques able to discriminate optical bit words in real time are presented. Discrimination capability of different correlators, both in free space architectures and in delay lines structures, is theoretically and experimentally analyzed. Experimental performances in word recognition are shown in the case of a volume hologra...
متن کاملOptical time-domain analog pattern correlator for high-speed real-time image recognition.
The speed of image processing is limited by image acquisition circuitry. While optical pattern recognition techniques can reduce the computational burden on digital image processing, their image correlation rates are typically low due to the use of spatial optical elements. Here we report a method that overcomes this limitation and enables fast real-time analog image recognition at a record cor...
