Radio Signal Generation over Fiber by Optical Injection Locking

Evaluation of 1 Tbit/S WDM-Oil-TDM-Pon Performance on 28 GHZ Frequency Band

“…In this paper we use Optical Injection Locking (OIL) method where two slave lasers are correlated and controlled by a master laser [11] [13]. Conombo et al [13] have shown that when the master laser signal of f p frequency is modulated by a signal of f m frequency, one can obtain, by the OIL method, an integer number of the f m frequency. f RF =2nf m where n is the number of the harmonic on witch a slave laser is hooked.…”

“…Each sub-module (Fig. 6) will optically lock by injection one of the four composite optical signals, will be controlled by the corresponding master laser (master laser and sub-modules are in the same frequency band) and will deliver at its output the 28 GHz 1282 signal whose principle is explained in [13]. Signals from the four sub-modules are recombined by a power combiner to obtain the 28 GHz modulated composite optical signal.The composite optical signal modulated at 28 GHz is injected into the transmission block which consists of fibers in the case without amplification or fibers, possibly control loop, amplifiers,...

“…Passive Optical Networks (PON) and the convergence network technology ROF (Radio Over Fiber) are part of the solutions proposed by scientists to provide high throughput to customers in the most remote areas [1] [10]. Our proposal focuses on the performance study of a hybrid network based on WDM-OIL-TDM hybrid PON in order to guarantee the effectiveness of this deal.That architecture combines bothWavelength Division Multiplexing (WDM),OpticalInjectionLocking (OIL) [11] [13]which is part of signal generation methods in Radio on Fiber (RoF) [11][13].technology and Time Division Multiplexing (TDM) in a single PON, offering reduced phase noise, negligible chromatic dispersion, reduced cost, high scalability and increased data rates. The Optical Injection Locking (OIL) method is used to generate a millimeter wave at 28 GHz frequency band.…”
