## Abstract Two methods for fabrication of azimuthally symmetric longโperiod fiber gratings (LPFGs) with CO~2~ laser are presented. These methods are based on symmetric exposure of the laser beam and rotation of the fiber, and the measured polarizationโdependent losses (PDL) are comparable to that

## Abstract An accelerometer based on the strain and bend characteristics of long period fiber grating (LPFG), which fabricated in common communication optical single mode fiber by using CO~2~ laser pulses, is investigated in this article. The relationship between vibration of the uniform strength
In this paper, we report novel long-period fiber gratings (LPFGs) fabricated by using a new writing technique that is mainly based on the thermal shock effect of focused high-frequency CO 2 laser pulses at several kHz. Several unique characteristics of these LPFGs, such as bend and transverse-load,
The paper deals with the fabrication of long-period gratings (LPG) in special optical fibers with an inverted parabolic-index profile of the cladding by periodically exposing the fibers to radiation of a high-power CO 2 laser. Details on the fiber fabrication and preparation of LPGs with a period of
