We present femtosecond laser inscribed phase masks for the inscription of Bragg gratings in optical fi bres. The principal advantage is the flexibility afforded by the femtos econd laser inscription, where sub-surface structur es define the phase mask period and mask properties. The masks are used to produce fibre Bragg gratings having different o rders according to the phase mask period. The work demonstrates the incredible flexibility of femtosecond lasers for t he rapid prototyping of complex and reproducible mask struct ures. We also consider three-beam interference effe cts, a consequence of the zeroth-order component present i n addition to higher-order diffraction components. |
