Recent advances in long dispersion compensating fibre Bragg gratings

Phase encoding and decoding of short pulses at 10 Gb/s using superstructured fiber Bragg gratings

“…The SSFBGs were written using the continuous grating writing technique [12]. This technique allows flexible tailoring of the FBG amplitude and phase characteristics, as the gratings are written plane by plane; hence, there is no need for specially patterned phase masks.…”

Advances in high-power short-pulse fiber laser systems and technology (Invited Paper)

“…The CFBGs presented here have acceptance bandwidths of up to 18nm and were produced using a scanning technique previously developed to produce precision gratings for telecommunication applications [10,11]. A CFBG with 2 nd and 3 rd order dispersion matched to a bulk grating has previously been demonstrated in a CPA system at 1550nm [12], but the maximum energy and minimum pulse duration will be limited using Er compared to Yb amplifiers.…”

Demonstration of a full-duplex bidirectional spectrally interleaved OCDMA/DWDM system

“…The peak reflectivity of all of these gratings is 25%. The gratings were fabricated using our continuous grating writing technique requiring only a single uniform-pitch phase mask [4], [5]. This technique has the accuracy to allow for excellent control of the amplitude and phase of the refractive index modulation along the grating length.…”
