文摘
- •
Phase-shifted fiber Bragg grating inscription by femtosecond laser is proposed.
- •
Two or three dips are observed by controlling the laser exposure intensity and time.
- •
The induced refractive index modulation of 6.3×10−4 is achieved.
- •
These PS-FBGs show good temperature, strain and pressure characteristics.
