Abstract

Effects of intensity modulation of light source on fiber distributed sensors based on Brillouin optical correlation domain analysis (BOCDA) are analyzed by numerical simulation, and the results are compared with reported experimental results. We show that the shape of the Brillouin gain spectrum in the BOCDA system has a particular dependence on the optical spectrum of the light source, and that it can be controlled and tailored by a proper modification of the optical spectrum using the intensity modulation.
