title: Design and fabrication of a blazed replica grating coupler for optical waveguides.
abstract: Replica grating couplers are useful for efficiently and inexpensively coupling a laser beam into a thin-film optical waveguide. Couplers have been designed, fabricated, and attached to optical waveguides. Input-coupling efficiencies as high as 75% have been measured on couplers having good uniformity over the entrance aperture.
