Ultra-wideband white noise generation apparatus based on chaotic micro-ring optical frequency combs

An ultra-wideband white noise generation apparatus based on chaotic micro-ring optical frequency combs, comprising m semiconductor lasers, micro-ring resonators consistent with the semiconductor lasers in quantity, and a photoelectric detector, wherein the semiconductor lasers, the micro-ring resonators, and the photoelectric detector all are integrated on a same chip substrate, and the semiconductor lasers, the micro-ring resonators, and the photoelectric detector are connected through optical waveguides with each other;

• the semiconductor lasers outputs continuous light, and the continuous light is injected into the micro-ring resonators through transmission of the optical waveguide, the continuous light has a combined effect of a series of non-linear effects and chromatic dispersion in the micro-ring resonators, resulting in spectrum widening;
• chaotic optical frequency combs at an equal interval are outputted via through ports of the micro-ring resonator;
• a radius of the micro-ring resonators is designed to generate the chaotic optical frequency combs with different free spectral ranges, the chaotic optical frequency comb generated in each of the micro-ring resonators is coupled to one waveguide and is then inputted into the photoelectric detector, and finally, an ultra-wideband white noise is outputted from the photoelectric device.
