| Title: | Bulk regeneration of optical fiber Bragg gratings | Authors: | Shao, L Wang, T Canning, J Cook, K Tam, HY |
Issue Date: | 20-Oct-2012 | Source: | Applied optics, 20 Oct. 2012, v. 51, no. 30, p. 7165-7169 | Abstract: | The reliability and reproducibility of regenerated gratings for mass production is assessed through simultaneous bulk regeneration of 10 gratings. The gratings are characterized and variations are compared after each stage of fabrication, including seed (room-temperature UV fabrication), regeneration (annealing at 850°C), and postannealing (annealing at 1100°C). In terms of Bragg wavelength (λ [sub B]), the seed grating variation lies within Δλ[sub B] = 0.16 nm, the regenerated grating within Δλ[sub B]= 0.41 nm, and the postannealed grating within Δλ [sub B] = 1.42 nm. All the results are within reasonable error, indicating that mass production is feasible. The observable spread in parameters from seed to regenerated grating is clearly systematic. The postannealed spread arises from the small tension on the fiber during postannealing and can be explained by the softening of the glass when the strain temperature of silica is reached. | Keywords: | Fiber Bragg gratings Machine tools Production engineering Silica |
