The principal advantage is the flexibility afforded by the femtosecond laser inscription, where sub-surface structures define the phase mask period and mask properties. The masks are used to produce fibre Bragg gratings having different orders according to the phase mask period. The work demonstrates the incredible flexibility of femtosecond lasers for the rapid prototyping of complex and reproducible mask structures. We also consider three-beam interference effects, a consequence of the zeroth-order component present in addition to higher-order diffraction components. 2012 SPIE. | ISBN: | 978-081949103-9 | ISSN: | 0277-786X | DOI: | 10.1117/12.975102 | Rights: | © 2012 SPIE. | Type: | Conference Papers | Affiliation: | Aston University Cyprus University of Technology Frederick University |
