Abstract

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 CO₂ laser with point-by-point technique. By introducing the 3π/2, π, or π/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 gratings is about 8.8 pm/°C at a temperature range of 23°C - 190°C. 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.
