Abstract

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‐methoxybenzo[c][1, 2, 5]thiadiazol‐4‐yl)acrylonitrile (BTD2CF3 ) displaying bright yellow (λ1 ) fluorescence with blue‐emitting (λ2 ) BPP and cyan emitting (λ3 ) DBA crystals using AFM‐tip provides a composite organic crystal multiplexer. The constructed hybrid single crystal multiplexer effectively transduces three optical signals (λ1 +λ2 +λ3 ) 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. Abstract : Mechanical integration of three optically different flexible crystal waveguides produces a compact organic wavelength division multiplexer (WDM). This WDM merges three narrow‐band optical signals (blue, cyan, and yellow) to transmit a broadband visible light signal. Such wide bandwidth signal multiplexers open the doors to visible light communication (VLC) technologies.
