Abstract

Motivated by the nonlinear phase measurements in rare-earth-doped fibers reported by Digonnet, et al (J. Lightwave Technol. 15, 299 (1997)), I provide theoretical evidence of passive synchronous phasing in ytterbium-doped multi-core fiber laser arrays of up-to 7 cores due to the existence of a negative resonant nonlinear index to which transitions at UV frequencies contribute. The effect appears to become more elusive with increasing array size, and confirmation for a 19-core array, for example, is still sought.
