A new method for generating frequency diverse two-component optical combs is proposed. The method is based on converting a laser carrier in a single amplitude Mach–Zehnder modulator by means of dual-frequency radio signal. Its application in a 5G communication system built on a medium-altitude unmanned aerial vehicle platform is considered. The method allows for flexible radiation pattern formation of frequency diverse antenna arrays in the radio range for communication with a low-altitude unmanned aerial vehicle swarm and for initializing communication channels between unmanned aerial vehicles of the platform to organize an optical transport domain.
