A Broadband, Multiplexed-Visible-Light-Transport in Composite Flexible-Organic-Crystal Waveguide

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 (BTD2CF(3)) displaying bright yellow (lambda(1)) fluorescence with blue-emitting (lambda(2)) BPP and cyan emitting (lambda(3)) DBA crystals using AFM-tip provides a composite organic crystal multiplexer. The constructed hybrid single crystal multiplexer effectively transduces three optical signals (lambda(1)+lambda(2)+lambda(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.

Automated summary

We present the construction of an organic crystal multiplexer using three chemically and optically different acicular, flexible organic crystals for broadband visible light signal transportation. By mechanically integrating the crystals, a hybrid single-crystal multiplexer is formed, which effectively transduces three optical signals to a composite output signal within a specific wavelength range, demonstrating the potential of organic flexible crystal waveguides for visible light communication technologies.
