摘要

We demonstrate the first fabrication of highly-compact and temperature-insensitive phase-shifted and multiple phase-shifted long-period gratings using the focused pulses of CO_2 laser with point-by-point technique. B y introducing the 3π/2, π, or ?/2 phase shifts in the different location of the gratings with 480 μm of a period-length and total number about 16-21 periods, the symmetrical and asymmetrical pandpass filters based on those gratings can be obtained. The temperature sensitivity of formed g ratings is about 8.8 pm/℃ at atemperature range of 23 ℃ - 190 ℃. Such fiber grating component could be used as an all-fiber oscillator in the laser cavity. Long-period gratings with different phase shifts are also investigated with various notches of resonance attenuations. All gratings fabricated are compactness to be packaged into the fiber-optic based devices.
