Device and method for producing all-optical high-speed random number based on chaotic laser

Abstract

A method for producing all-optical high-speed random number based on chaotic laser comprises the steps that produced chaotic laser is sampled by utilizing an all-optical sampling system based on a semiconductor optical amplifier-nonlinear polarization rotation effect (SOA-NPR), an all-optical quantizer based on the nonlinear polarization rotation effect (NPR) is utilized to quantize the pulse obtained after sampling, and the random number is obtained in an optical domain. The devices adopted in the method include a chaotic laser source, an all-optical sampler and the all-optical quantizer. The method is completely performed in the optical domain, the electronic bottleneck limitations can be broken through, and all-optical high-speed random codes are produced in real time. The produced random codes can be directly compatible with optical signals in an optical communication network, and the demand for modern high-speed communication safety is met.
