The design of multicore fiber for high power fiber lasers development



  1. Inner Mongolia University of Science and technology, Baotou 014010, China


Design of evanescent-wave-coupled (EWC) multicore fiber laser based on finite element method was presented. By optimizing design parameters, in-phase mode becomes the unique supermode and therefore exhibits much high coupling strength of about 80%. Fundamental LP01 mode with a large effective area of 13063 µm2 , relatively good beam quality factor of 2.64, and small confinement coefficient of 0.003 dB/km corresponding to EWC 19-core fiber, shows much better characteristics than other fibers. Results demonstrate that this structure is proposed to be a potential system for high power fiber laser.
