Paper Abstract

Using a femtosecond laser source waveguide, Bragg grating and waveguide-Bragg grating (WBG) structures have been written in fused silica and undoped phosphate glasses. The WBG devices are written using a slit focusing geometry and point-by-point grating inscription method. They demonstrate Bragg reflectivities at the design wavelength (1550 nm) and have been used as a new method for estimating the minimum refractive index change induced during the waveguide writing process.
