Phase encoding and decoding of short pulses at 10Gb/s using superstructured fiber Bragg gratings [PDF]
, 2001 A 7-chip, 160-Gchip/s phase-shift keyed code is assigned to short pulses after reflection from a superstructured fiber Bragg grating. The code is then recognized by a second grating, which is nominally identical to the encoder grating.

Writing Bragg Gratings in Multicore Fibers [PDF]
Journal of Visualized Experiments, 2016 Fiber Bragg gratings in multicore fibers can be used as compact and robust filters in astronomical and other research and commercial applications. Strong suppression at a single wavelength requires that all cores have matching transmission profiles. These gratings cannot be inscribed using the same method as for single-core fibers because the curved ...

Regeneration of tilted fiber Bragg gratings
SPIE Proceedings, 2014 The regeneration of Tilted Fiber Bragg Gratings photowritten in a singlemode SMF-28e fiber is investigated. Three tilted FBGs, with respectively 0°, 4° and 8° external tilt angles are annealed according to a conventional high temperature regeneration protocol.

Formation and Applications of the Secondary Fiber Bragg Grating [PDF]
Sensors, 2017 Being one of the most proven fiber optic devices, the fiber Bragg grating has developed continually to extend its applications, particularly in extreme environments. Accompanying the growth of Type-IIa Bragg gratings in some active fibers, a new resonance appears at the shorter wavelength.
