Abstract We report the construction of an organic crystal multiplexer using three chemically and optically different acicular, flexible organic crystals for a broadband, visible light signal transportation. The mechanical integration of a highly flexible crystal waveguide of ( Z )‐2‐(3,5‐bis(trifluoromethyl)phenyl)‐3‐(7‐methoxybenzoc1,2,5thiadiazol‐4‐yl)acrylonitrile (BTD2CF 3 ) displaying bright yellow (λ 1 ) fluorescence with blue‐emitting (λ 2 ) BPP and cyan emitting (λ 3 ) DBA crystals using AFM‐tip provides a composite organic crystal multiplexer. The constructed hybrid single crystal multiplexer effectively transduces three optical signals (λ 1 +λ 2 +λ 3 ) covering the 420–750 nm region as a composite output signal. The presented proof‐of‐principle experiment demonstrates the real potential of organic flexible crystal waveguides for visible light communication technologies.
