Enhanced stimulated Brillouin scattering threshold through phase control of multitone phase modulation

Abstract

We show that controlling the phase difference among the various tones of a multitone phase modulator can substantially increase the stimulated Brillouin scattering (SBS) threshold during optical fiber transmission. We present detailed modeling and experimental validation of the effect. This result should be especially useful for optical networks requiring high signal launch power. © 2010 Society of Photo-Optical Instrumentation Engineers.
