Radio Signal Generation over Fiber by Optical Injection Locking

Advancement in digital optical communication over long-haul access and access networks is fostering the emergence of millimeter-wave technologies that will enable transport of fast enough data streams in the future. To connect remote users, these signals are used in converging optical/wireless technologies by integrating Worldwide Interoperability for Microwave Access (WiMax), Wireless Fidelity (WiFi), Long Term Evolution (LTE) and currently 5G technologies. The optical injection locking (OIL) method is studied by applying the correlated system technique of two slave lasers controlled by a master laser. The theoretical and experimental demonstrations consisted in generating several times the reference frequency fm of the desired RF (radio frequency) signal. Optisystem software was used for the simulation.
