Popis:	Experimental results of 1‐to‐2 intraplane and of 1‐to‐32 interplane V‐shaped fanouts are delineated. Coupling efficiencies of 48% for surface‐normal and of 45% for near‐surface‐normal interplane fanout beams are theoretically and experimentally confirmed. The influence of the angular fluctuation of a device having two multiplexed waveguide holograms with film thickness of 15 μm and index modulation of 0.04 is studied. The angle between the two grating vectors is determined to be less than 26° to keep the near‐surface‐normal fanout beams.
