## 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
From the angle of sensitivity of the LPFG resonant transmission spectrum, we demonstrate the sensitivity of LPFG resonance peak amplitude changing with transverse load and its direction correlation. The design of a miniaturized resonant peak modulation-based LPFG asphalt pavement pressure sensor is
## Abstract We present a novel method to fabricate fiber filters based on mechanically induced longโperiod fiber gratings. Transmission spectra can be tailored by external pressures or by introducing a phaseโshift. As an example, the filter was used to flatten the spectral output from an Erโdoped s
A novel wavelength-selective all-fiber filter using a single long-period fiber grating (LPG) interacting with a misaligned fusion splicing point has been demonstrated. The misaligned splicing point couples a part of the core mode power into the cladding modes, which is then recoupled into the core m
