| contents | Organic crystal waveguides, known for excellent light-guiding and photonic versatility, present a promising alternative to conventional optical media in visible light communication (VLC) systems. In a novel approach, the high photoluminescence quantum yield organic crystal 2,2dash-((1E,1Edash)-hydrazine-1,2-diylidenebis(methaneylylidene))diphenol (SAA) is used as an optical waveguide medium for real-time data communication in the visible range, employing a microcontroller unit with on off keying modulation. Leveraging its spectral properties, the SAA crystal demonstrates dual active and passive waveguiding capabilities for signal modulation. Error-free signal detection is achieved thanks to the smooth, defect-free surface morphology of the crystal. The relationship between incident angle and light intensity reveals stable fluorescence under narrow angle excitation, positioning the crystal as an all-angle signal receiver that surpasses conventional optical fibers. A real time data transfer setup is demonstrated, enabling direct transmission from a serial interface and accurate reconstruction of grayscale images. This represents the first implementation of a fully organic crystal-based VLC platform, integrating wavelength conversion, omnidirectional waveguiding, and real time signal processing. The results establish a foundation for compact, efficient, and integrable photonic communication technologies. |
