Phase-locked supermode emissions from a dual multicore fiber laser

We report on a fiber laser configuration, emitting two phase-locked and single mode beams at the output of two multicore fibers. The passive technique is based both on the selective excitation of the only in-phase supermodes of the multicore fibers and on an intra-cavity angular filtering of the emi...

Summary:We report on a fiber laser configuration, emitting two phase-locked and single mode beams at the output of two multicore fibers. The passive technique is based both on the selective excitation of the only in-phase supermodes of the multicore fibers and on an intra-cavity angular filtering of the emitted beams to provide phase control. As a proof of principle, we experimentally demonstrate the coherent combining of the fundamental in-phase supermodes of two parallel 7-cores fibers.
