Paper Abstract

Multicore fiber-lasers are designed to build high-power short length fiber-lasers. In our case the active single- mode cores (micro cores) are placed on a ring inside a big pump core. The micro cores are placed together very closely so that evanescent coupling between adjacent micro cores should be provided. To understand the coupling behavior in a multicore fiber in order to phase-lock all the micro cores we measured experimentally the coupling constant between the micro cores. Simultaneously we calculated the evolution of an injected field in a multicore fiber. In the experiment and in the simulations 38 micro cores with a diameter of approximately 6.9 micrometers are placed on a ring with a diameter of 115 micrometers . The distance between adjacent cores is about 2.6 micrometers . The measured coupling constant of 2cexp equals 0.82 mm-1 is in good agreement with the value 2cth equals 0.83 mm-1. Furthermore the phase evolution in each micro core was evaluated.
