Two chaotic synchronizations in er-doped fiber lasers and their application in two-channel coding secure communications [PDF]

ITM Web of Conferences, 2022
A dual-ring erbium-doped fiber laser has nonlinear dynamic characteristics based on optical coupling interaction of lasing from the two laser rings and can send chaotic lasing to encode and mask an information to perform secure communication.
