Abstract

AbstractCombining the advantageous properties of cyclo olefin copolymers (COC) with a rapid UV laser based fabrication process, we highlight the generation of planar waveguide Bragg gratings suitable for multi‐axial strain sensing (Fig. 1). Bragg gratings are optical filters reflecting a small wavelength band, which is determined by the spatial grating period and the effective refractive index. As both determining factors depend, e. g., on mechanical load conditions and temperature, measuring the reflected Bragg wavelength facilitates optical sensing of these conditions.
