Automated system for trans-jacket fibre Bragg grating inscription and manufacturing

An alignment system for use in an ultrashort pulse duration laser-based Fiber Bragg Grating (FBG) writing system, the electromagnetic radiation having a pulse duration of less than or equal to 5 picoseconds, and the wavelength of the electromagnetic radiation having a characteristic wavelength in the wavelength range from 150 nm to 3.0 microns, the alignment system comprising:

• a holder configured to hold an optical fiber in a position perpendicular to a beam path of an ultrashort pulse duration laser-based FBG writing station;
• an optical detector;
• and
• a control system with an input from the optical detector and an output to adjust parameters of an optical writing source and the FBG writing station based on photoluminescence generated in the optical fiber as indicated in a signal received at the input from the optical detector.
