Abstract
We propose an in-line wavelength selective core switch for
multicore fiber (MCF) transmission systems, based on the acousto-optic
effect. A theoretical model addressing the interaction between flexural
acoustic waves and the optical signal in MCFs is developed. We show that
an optical signal propagating in a particular core can be switched to any
other core or distributed over all the cores. By tuning the acoustic wave
amplitude, we can adjust the amount of optical power transferred between
the cores
