This paper presents a systematic review of long period fiber gratings (LPFGs) written by the
CO 2 laser irradiation technique. First, various fabrication techniques based on CO 2 laser …

We report, for the first time to our knowledge, the excellent optical performance of long-
period gratings written in three standard fibers and in two nonstandard fibers, namely, S …

Thermal diffusion is the phenomenon of the migration of dopants in an optical fiber during
high-temperature treatment. Research on the theory and technique of optical fiber thermal …

We present an overview of the applications of the electric arc technique related to optical
fibre technology. The use of arc discharges ranges from the well-known fibre splicing, going …

Electric arc-induced long-period fiber gratings, with low insertion loss (< 0.2 dB) and high
isolation peaks (− 24 dB), have been fabricated in standard single-mode fiber (Corning …

The method of femtosecond laser inscription by slit-apertured beam is applied for fabrication
of long-period fiber gratings in polarization-maintaining Panda-type fiber. Polarization …

Long-period fiber gratings (LPGs) have been inscribed in nitrogen-doped fibers by electrical
arc discharge. The influence of drawing tension as well as external load applied during arc …

A highly sensitive two-axis bending sensor based on long period fiber grating (LPFG) in a
dual side-hole fiber (DSHF) is presented and experimentally investigated. The LPFG is …

We experimentally demonstrate an automatic arc discharge technology for inscribing high-
quality long period fiber gratings (LPFGs) with greatly improved inscription efficiency for …

The article overviews the main properties, fabrication techniques and ares of application of
long-period fiber gratings. The basic theoretical equations describing spectral properties of …
