Efficient coupling of a laser to a waveguide using a taper designed by conformal mapping

Ash, A E; Austin, M; Love, John


Maximizing the optical power collected in a waveguide from the diffracting field of a semiconductor laser is desirable in optical fibre communication systems. However, the spot size and phase front curvature of the laser field usually makes a poor overlap with the mode of the receiving waveguide. Various proposals have been made to improve this coupling. This paper presents the design of a tapered waveguide section, having the correct geometry and refractive index profile, to efficiently...[Show more]
