A new reactive multicomponent polymeric system is presented for the real-time optical recording of volume phase holograms integrated in waveguiding thin films. Efficient Bragg-effect grating couplers are produced holographically. In a multimode planar waveguide, the input coupling efficiency reaches 62% for an incident 633-nm He–Ne laser beam. Almost 96% of the mode power is emitted by a second coupler into one single-output beam.
