Paper Abstract

Inscription of Bragg grating structures is reported in inexpensive multimode borosilicate fibers using femtosecond pulse duration 800 nm infrared radiation and a phase mask. Thermal annealing of the gratings up to 700 °C reveals a behavior similar to Type I-IR gratings made in silica fiber with ultrafast infrared radiation. A portion of the index modulation of the grating is stable up to 500 °C. Below 100 °C, the wavelength shift of the Bragg grating is characterized by ~ 12 pm/°C slope. Above 300 °C, the wavelength shift is ~ 5 pm/°C.
