| dc.description.abstract | 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 π 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 × 10^(−5) is inferred from the polarization-induced spectral shifting of the PSBGW narrowband filters. | en |
