A Chameleon-like Core-Shell Organic/Lanthanide Flexible Crystal Waveguide for Bandwidth and Colour Tunability

Key Points

• The main aim is to develop an optical fiber that mimics chameleon color changes for tunable spectral signaling.
• Developed a flexible crystal waveguide with core-shell structure using lanthanide materials.
• Conducted experiments on input-induced changes in spectral output across visible spectrum.
• Analyzed bandwidth and color tunability properties through various signal inputs.
• Achieved significant color tunability with a responsive range of wavelengths (400-700 nm) based on input signals.
• Demonstrated dynamic adjustment of bandwidth, improving signal quality with a variation rate up to 75%.
• Showed potential application for real-time optical communications, enhancing system performance.
