Point-by-point inscription of first-order fiber Bragg grating for C-band applications.
The influence of the fiber geometry on the point-by-point inscription of fiber Bragg gratings using a femtosecond laser is highlighted. Fiber Bragg gratings with high spectral quality and strong first-order Bragg resonances within the C-band are achieved by optimizing the inscription process. Large birefringence (1.2x10(-4)) and high degree of polarization-dependent index modulation are observed in these gratings. Potential applications of these gratings in resonators are further illustrated.
