title: Ultra-high temperature chirped fiber Bragg gratings produced by gradient stretching of viscoelastic silica.
abstract: By applying a suitable quadratic temperature distribution at a temperature within the viscoelastic softening region for silica, a regenerated chirped grating with bandwidth of 9.8 nm is produced from a uniform grating using post strain-tuning under load. Simulated and experimental results are in good agreement.
