Abstract
Stimulated Brillouin scattering (SBS) limits the power that may be transmitted through an optical fiber because the pump is depleted as energy is transferred into the backward traveling Stokes wave. SBS occurs when the power in the pump wave exceeds a threshold power. The SBS threshold can be easily exceeded in practical contexts (e.g. 4 mW in a typical telecommunication fiber, 25 km in length). The SBS threshold can be increased by increasing the optical bandwidth of the pump wave. In this work, we propose and demonstrate a novel scheme for suppressing stimulated Brillouin scattering in optical fiber. We show that Boolean chaotic phase modulation, which is easily generated with a field-programmable gate array (FPGA), can raise the SBS threshold by \({>}12\) dBm.
