Bio‐Inspired Band‐Gap Tunable Elastic Optical Multilayer Fibers. (27th January 2013) - Kolle, Mathias
Abstract The concentrically‐layered photonic structure found in the tropical fruit Margaritaria nobilis serves as inspiration for photonic fibers with mechanically tunable band‐gap. The fibers show the spectral filtering capabilities of a planar Bragg stack while the microscopic curvature decreases the strong directional chromaticity associated with flat multilayers. Elongation of the elastic fibers results in a shift of the reflection of over 200 nm.
