Conception and automatisation of a tunable Phase-Mask Interferometer for Fiber Bragg Grating inscription

Optical fiber Bragg gratings (FBG) have become ubiquitous in many products such as lasers, filters and sensors. However, typical commercial products are becoming more complex, ones that require highly competent operators since many parameters need to be fine-tuned during the writing of quality FBGs. A previous Mitacs project successfully addressed several challenges in the conception of a FBG writing system based on scanning tunable Phase-Mask Interferometer, marketed by PhotoNova as the BraggTune, using different UV lasers. However, many challenges remain to make the commercial unit more versatile, precise and easier to use with semi-automation, removing the uncertainty of manual mechanical tuning, as in the present product. In the first phase, the flexibility and the ease of use of the device by automating the existing product enabling fabrication of different types of FBGs will be researched. TO BE CONT’D
