Photonic Generation of Triangular Shaped Microwave Pulses Using Stimulated Brillouin Scattering (SBS)

Abstract

. A triangular shaped microwave pulse is generated by optical heterodyning principle using Stimulated Brillouin Scattering (SBS) in an optical fiber communication link. A narrowband Distributed Feedback (DFB) Laser diode of wavelength 1552.52 nm, LiNbO Mach Zehnder Modulator (MZM), Highly Nonlinear Fiber (HNLF) of length 20 Km and Optical receiver that comprise high power optical pump source, circulator, PIN photo detector and Band pass filter form the link. Finally, a Radio over Fiber system for the generation of triangular shaped microwave pulse is built through simulation.
