Abstract
A fiber coupler () for coupling a plurality of cores () of a multi-core optical fiber () to an integrated photonic device comprises a grating array comprising a plurality of polarization splitting gratings () arranged in a manner that corresponds to the plurality of cores () in the multi-core optical fiber (). The fiber coupler () also comprises first and second mode converters () extending from first and second sides of each of the plurality of polarization splitting gratings () to receive first and second polarization modes of the optical signal scattered by the polarization splitting grating (). A plurality of waveguides (--) extends from ends of each of the mode converters () to guide a single polarization mode of one of the optical signals.
