Abstract
The invention relates to a coupling device for an optical waveguide, using a hologram recorded in a photoresist layer arranged on a face of the waveguide, and capable of coupling a wave having a predetermined wafe front and travelling outside the waveguide and a plane wave travelling inside the guide. The invention also describes a holographic method for manufacturing such a coupling device.
