“…Another solution based on the beating signals is explained in Reference [ 64 ]. The authors developed a dual-frequency optoelectronic oscillator (OEO) as an interrogation system incorporating two phases shifted FBGs (PSFBGs) one of which used as reference while the other is the strain sensing element.…”

Fibre Bragg grating (FBG) strain sensors are not only a very well-established research field, but they are also acquiring a bigger market share due to their sensitivity and low costs. In this paper we review FBG strain sensors with high focus on the underlying physical principles, the interrogation, and the read-out techniques. Particular emphasis is given to recent advances in highly-performing, single head FBG, a category FBG strain sensors belong to. Different sensing schemes are described, including FBG strain sensors based on mode splitting. Their operation principle and performance are reported and compared with the conventional architectures. In conclusion, some advanced applications and key sectors the global fibre-optic strain sensors market are envisaged, as well as the main market players acting in this field.

“…The MPF with high quality factor or narrow bandwidth can provide high frequency selectivity, spectral purity, resolution and bandwidth to overcome the limitations of electronic approaches [3]. Due to these advantages, the MPF is a significant component for optoelectronic oscillators (OEO) [4], microwave signal measurements [5,6] and target identification radar systems [7], etc. Recently, to meet the increasing demand for multiband or multifunction filters, many approaches have been proposed to realize multiple-passband MPFs [4,[8][9][10][11][12].…”

This paper proposes a tunable multiple-passband microwave photonic filter (MPF) that is incorporated with an injection-locked Fabry-Pérot (FP) laser. In the proposed MPF, multiple passbands can be easily generated based on the frequency-selection effects of the laser structure in the case of multiple light waves injection. The novelty here is that the obtained multiple-passband MPF can achieve either a dual-passband or a single-passband by using merely one experimental scheme. Moreover, since the laser injection ratio of the proposed scheme is high, the central frequency of each passband has a large tunable range. More tunable passbands can be generated by employing more external wavelengths. By finedetuning the injection parameters, the frequency tuning range of 17 GHz and the out-of-band rejection ratio of 24.1 dB are achieved for the dual-passband MPF, and the out-of-band rejection ratio of 22 dB and the 3-dB bandwidth of 360 MHz are achieved for the singlepassband MPF. In addition, the attained peak power and bandwidth of the proposed MPF are investigated with respect to the injection parameters, including detuning frequency, injection ratio and bias current of FP laser. The stability and dynamic range of the MPF are also evaluated through experiments.

“…Special attention must be paid to the sensing field, where PS-FBGs find applications to detect ultrasound [5], pressure [6], and temperature [7], among others. Moreover, very recently published papers report that PS-FBG also find applications in the microwave photonics field, such as a tunable bandstop-to-bandpass microwave photonic filter [8] or a high resolution strain interrogation system based on two phase-shifted FBGs in a dual frequency optoelectronic oscillator [9]. Moreover, as reported in the previous literature, multiple phase shifts can be used to tailor the transmission spectrum for wavelength demultiplexing in DWDM applications [10][11][12].…”

In this contribution we report on the fabrication of novel bandpass transmission filters based on PS-FBGs in microstructured polymer fibers at telecom wavelengths. The phase mask technique is employed to fabricate several superimposed gratings with slight different periods in order to form Moiré structures with a single or various π phase shifts along the device. Simulations and experimental results are included in order to demonstrate very narrowband transmission filters. Experimental characterization under strain and temperature variations is provided in a non-annealed fiber and time stability of the fabricated devices has been also measured under different pre-strain conditions.
