Abstract

We investigate the possibility of phase locking in a multicore photonic crystal fiber. We analyze the modal behavior of photonic crystal fibers with two and six cores and compare them with the usual single-core case. We also show how the strength of the coupling among modes belonging to different cores can be controlled by adjusting the size of the airholes between the waveguiding cores. We then analyze the Talbot effect in the case of the six-core photonic crystal as a pseudoperiodic structure and show that there exists the possibility of using a Talbot resonator to achieve phase locking in multicore photonic crystal fibers.
