1. A device, comprising:
a generator that facilitates generation of a first electromagnetic wave;
a core comprising a first region, a second region and a third region; and
a waveguide that facilitates guiding the first electromagnetic wave towards the core, the first electromagnetic wave inducing at the first region a second electromagnetic wave,
a portion of an inner surface of the waveguide comprising a first tapered structure to reduce a reflection by the first electromagnetic wave at an outer surface of the core,
the waveguide confining the second electromagnetic wave at least in part within the core in the first region, the second region being located within the waveguide, the second electromagnetic wave propagating along the second region and expanding,
the third region not being located within the waveguide, the second electromagnetic wave propagating along the core in the third region, and the second electromagnetic wave being directed to another device coupled to the core in the third region.
