Organic Crystal VLC Platform

This design project features an organic crystal-based platform used for encrypted visible light communication (VLC) via all-angle fluorescence signal reception and waveguiding. The 3D visuals illustrate the integration of a high quantum yield organic crystal (SAA) as a waveguide and optical receiver, capturing modulated input signals without the need for fiber optics or alignment optics. Designed to simulate real experimental layouts, the models depict the laser excitation, wide-angle incidence, and light emission pathways across the crystal surface, showcasing a compact and alignment-free photonic secure communication platform.
