<p>A device for optically coupling a dielectric optical wave guide to another optical device such as a detector, a laser or light amplifier characterized by a coupling element having either a refraction index or surface relief structure which is arranged as a layer extending circumferentially around the surface of the wave guide adjacent one end, and an optical component, such as an axicon, kinoform, a phase hologram or a volume hologram, having an axis of rotational symmetry which is arranged coaxially with the axis of the wave guide between the end and the optical device. To produce the device, the layer is applied on the wave guide and treated by exposing with an amplitude modulated light beam or an intensity modulated electron beam. After completing the treating by developing and fixing the exposed layer, an optical component is arranged on the desired position between the end of the wave guide and the optical device.</p> |
