Abstract

We report a fabrication technique for chirped fiber Bragg gratings (CFBGs) using a flexible setup based on a poly(methyl-methacrylate) phase mask. The period of the phase mask can be thermally tuned during the inscription process, allowing the grating period of uniform fiber Bragg gratings to be shifted about $7\mathrm{nm}$ by a temperature change of $74\mathrm{K}$. In addition, CFBGs with bandwidths up to $2\mathrm{nm}$ are demonstrated in nonphotosensitive fibers by IR femtosecond inscription.
