Abstract (EN): Phase-shifted Bragg grating waveguides (PSBGWs) were formed in bulk fused silica glass by femtosecond laser direct writing to produce narrowband (22 +/- 3) pm filters at 1550 nm. Tunable p and other phase shifts generated narrow passbands in controlled positions of the Bragg stopband, while the accurate placement of multiple cascaded phase-shift regions yielded a rectangular-shaped bandpass filter. A waveguide birefringence of (7.5 +/- 0.3) x 10(-5) is inferred from the polarization-induced spectral shifting of the PSBGW narrowband filters. (C) 2012 Optical Society of America
