Abstract
- The Guided Acoustic Wave Brillouin Scattering (GAWBS) in fibers will be excited at a low optical power level, which can cause large impairments on high-capacity spatial division multiplexing optical fiber communication, digital coherent transmission and optical quantum transmission. For spatial division multiplexing optical fiber communication system, we theoretically and experimentally investigate the characteristics of GAWBS in the self-made uncoupled seven-core four-mode fiber. The results indicate that, the cores exhibit the significant differences of GAWBS characteristics depending on their distances from the fiber center. In future, the disparate GAWBS noise compensation method for each core can be utilized to achieve a high signal-to-noise ratio for spatial division multiplexing transmission with low error rate.
