Abstract

Fiber Bragg gratings are embedded within 3D printed polymer packages. Information about both induced and applied stresses, and operator error, can be determined from the observed spectral shifts and chirping. A novel way to produce packaged broadband gratings, with $\Delta {\lambda _{\rm BW}}\gt {7}\;{\rm nm/cm}$, is proposed and demonstrated.
