Patent ID: 8548291

Claim:
An optical device, comprising: a first array of optical couplers located over a surface of a substrate such that the optical couplers of the first array are able to end-couple in a one-to-one manner to the optical cores of a first multi-core fiber having an end facing and adjacent to the first array and the surface; a second array of optical couplers located over the surface such that the optical couplers of the second array are able to end-couple in a one-to-one manner to optical cores having ends facing and adjacent to the second array; a plurality of optical waveguides being over the surface and connecting in a one-to-one manner the optical couplers of the first array to the optical couplers of the second array; and a plurality of pump couplers, each optical waveguide having a pump coupler connected thereto between the ends thereof.
