This study investigates the use of diffractive optical components for efficient, mode-matched optical fiber-to-waveguide coupling. In this study a single element, with diffractive lenses on both back and front surfaces, is designed, fabricated, and tested. The element transforms the optical beam profile exiting a laser diode from a divergent, elliptical mode profile into a collimated beam of circular mode shape. The output beam shape and optical efficiency of the diffractive element are measured. Test results agree favorably with expected values.
