Abstract
We present experimental results on the operation of a dissimilar two-core f iber segment as a channel-dropping filter based on the principle of grating -frustrated coupling, The restoration of 100% coupling by ultraviolet (UV)- tuning of the fiber is demonstrated over a bandwidth in excess of 20 nm. It is also shown that a grating can be inscribed in one of the cores while ma intaining perfect coupling conditions between the cores.
