Physical Insight into Dispersionless FBG Designs [PDF]

Advanced Photonics Congress, 2012
We provide physical insight into the role different sections play in inverse-scattering-designed dispersionless FBGs. Using this knowledge we design and fabricate strong (>30dB) bidirectional dispersionless filters.

A simple method for fabricating phase-shifted fibre Bragg gratings with flexible choice of centre wavelength [PDF]

, 2009
A simple technique for fabricating phase-shifted fibre Bragg gratings (PSFBGs) without the use of a phase-shifted phase mask is presented. Two, 3-mm long, standard fibre Bragg gratings (FBGs) were inscribed sequentially in singlemode fibre at the same
