PHOTONIC FIBER AND COLOR-CHANGING AND COLOR-TUNABLE PHOTONIC TEXTILE PRODUCT USING THIS PHOTONIC FIBER

摘要

A photonic bandgap fiber comprises a light-propagating core and a periodic reflector surrounding the core and defining at least one bandgap, wherein, in response to white light, only light at frequency located within the bandgap is guided. A photonic textile product comprises a textile material including photonic fibers structured to reflect light of a first given color in response to ambient illumination and to irradiate light which is guided within the photonic fibers, wherein the irradiated light has a second given color different from the first given color. A method of producing the photonic textile product and adjusting a color of the photonic textile product, comprises incorporating in the textile material the photonic fibers, controlling relative intensities of the reflected light of the first given color and the irradiated light of the second given color, and mixing the reflected light of the first given color and the irradiated light of the second given color to determine the overall color of the photonic fibers and textile material.
