In this study, we introduce visible light guiding optical fibers with underwater operational capability for subaquatic communication and sensing technologies. The fibers are composed of mechanically flexible, blue-violet fluorescent BPP crystal waveguides with high-aspect ratio, demonstrating their amphibian-like character in both ambient and underwater conditions. The high flexibility of the crystals allows for mechanical alteration of the fiber's output light direction, making them suitable for high-precision lighting and sensing applications. This development of multi-environment-compatible and mechanically flexible organic optical fibers as sensing materials has tremendous potential for short-range underwater photonic technologies.
Visible light guiding optical fibers with underwater operational capability are highly desired for subaquatic communication and sensing technologies. Herein, we present mechanically flexible, blue-violet fluorescent (4,4 '-bis(2,6-di(1H-pyrazol-1-yl)pyridin-4-yl)biphenyl) (BPP) crystal waveguides with high-aspect ratio. These milli-meter-long BPP crystals guide light actively and passively in ambient and underwater conditions demonstrating their amphibian-like character. Due to the crystal's high flexibility, the optical fiber's output light direction in submerged and ambient states can be altered mechanically for high-precision lighting and sensing applications. The development of such multi-environment-compatible and mechanically flexible organic optical fibers acting as sensing materials possess enormous potential for short-range underwater photonic technologies.
