Title:
FOUR-CHANNEL ULTRA-HIGH-SPEED TWO-WAY OTDM SECURE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/037245
Kind Code:
A1
Abstract:
Disclosed is a four-channel ultra-high-speed two-way OTDM secure communication system, comprising two optical fiber generation and wave division modules, two multiplexing delay and modulation modules, and two optical fiber beam splitting and modulation modules. According to embodiments of the present invention, the chaotic synchronization between two spinning VCSELs is implemented by performing external light injection on the two spinning VCSELs. The asymmetry of the two spinning VCSELs is caused by uneven propagation delay, such that such asymmetry is eliminated to a great extent by injecting elliptically polarized light into the two spinning VCSELs. Moreover, by means of further optimization of parameters, high-quality in-phase and anti-phase lead/lag chaotic synchronization is achieved, and four-channel ultra-high-speed two-way OTDM secure communication is achieved.
