In this paper, a single long-period fiber grating (LPFG) element written by focused high-frequency CO2 laser pulses is demonstrated for simultaneous measurement of transverse load and temperature, for the first time, to our knowledge. Temperature and

A novel tunable gain equalizer based on the LPFG induced by high-frequency CO2 laser pulses is demonstrated, for the first time, to our knowledge. The resonant wavelength and the resonant peak amplitude of the novel LPFG have a good linearity with te

We demonstrate a high-gain, low-noise in-line Er-doped optical fiber amplifier (EDFA) using a novel long period fibre grating written by high-frequency CO2 laser pulses. The optimization of such an EDFA has been investigated, for the first time, to o

A novel method based on combination of the bending and thermal characteristics of a new long-period fibre grating written on a photosensitive fibre by high-frequency CO2 laser pulses is proposed for the gain flattening of EDFAs. The gain profile was

A novel fibre-optic sensing system used for temperature- strain discrimination is presented. This system consists of an extrinsic Fabry-Perot interferometric sensor (EFPI) and a chirped in-fibre Bragg grating (CFBG) in series. The EFPI and the CFBG a

In this paper, we report novel long-period fiber gratings (LPFGs) fabricated by using an improved CO 2 exposure method, which is based on the thermal shock effect of high-frequency CO 2 laser pulses at several kHz. Compared with the method using low-
