“…However, the frequency difference between the Rayleigh and Brillouin scattering lights is much narrower in the wavelength domain. The FBG filter and the Mach–Zehnder interferometer [ 224 , 225 , 226 ] are generally used to separate the two frequency components. In addition, it is also practicable to process the scattering signal in the frequency domain.…”

Distributed optical fiber sensors (DOFSs) are a promising technology for their unique advantage of long-distance distributed measurements in industrial applications. In recent years, modern industrial monitoring has called for comprehensive multi-parameter measurements to accurately identify fault events. The hybrid DOFS technology, which combines the Rayleigh, Brillouin, and Raman scattering mechanisms and integrates multiple DOFS systems in a single configuration, has attracted growing attention and has been developed rapidly. Compared to a single DOFS system, the multi-parameter measurements based on hybrid DOFS offer multidimensional valuable information to prevent misjudgments and false alarms. The highly integrated sensing structure enables more efficient and cost-effective monitoring in engineering. This review highlights the latest progress of the hybrid DOFS technology for multi-parameter measurements. The basic principles of the light-scattering-based DOFSs are initially introduced, and then the methods and sensing performances of various techniques are successively described. The challenges and prospects of the hybrid DOFS technology are discussed in the end, aiming to pave the way for a vaster range of applications.

“…Besides, devices with multi-functionalities significantly reduce design and economic costs, time of fabrication cycles and energy. 11 Progress has been made in designing small-scale reconfigurable multi-functional devices based microring resonators for filtering, 12,13 microwave signal generation, transmission and processing based on monolithically integrated lasers and modulators, 14 large scale general purpose multi-functional processors 15 for microwave photonic signal processing, chemical and biomedical sensing, signal processing, multiprocessor networks, and quantum information systems and so on. However, large-scale general-purpose processors are complex in design, programmability, fabrication and operation.…”

We investigate the reconfigurable resonator based on five times self-coupled photonic waveguide for versatile functionalities. These include a high-performance notch filter, bandpass filters of Bessel and Chebyshev types with improved shape factors, extinction ratio (ER) of more than 40 dB, high Q-factors, tunable ultra-high sharp Fano resonances with slope rates exceeding 1000 dB/nm and high ERs, the optical analog of multi-band electromagnetically induced transparencies, and tunable true-time delay lines with a considerable delay range.

“…Fu et al [5] demonstrated a stable dual-wavelength thulium/holmium co-doped fiber laser with wavelength longer than 2 µm and a signal-to-noise ratio (SNR) of up to 50 dB using a cascaded SMS structure. Mach-Zehnder interferometers (MZIs) [7,8] have also been proven to the capable of generating dual-wavelength outputs. In this regard, Yan et al [9] incorporated an in-fiber acousto-optic MZI in their laser cavity to generate a tunable dual-wavelength output with a range of 30 nm and an adjustable spacing between the two output wavelengths of up to 2.65 nm.…”

In this work, we successfully demonstrated an all-fiber, dual-wavelength holmium-doped fiber laser (HDFL) with a tunable wavelength spacing range of 8 nm to 24 nm. The HDFL utilizes a Lyot filter to obtain a stable dual wavelength output, with the Lyot filter being constructed from a polarizer, a 20 m polarizing maintaining fiber (PMF) and two polarization controllers (PCs). The dual-wavelength HDFL has an operating wavelength range from 2072.1 nm to 2097.2 nm and a maximum spacing of 24 nm between the lasing wavelengths as well as a signal-to-noise ratio of up to 45 dB and a side mode suppression ratio as low as 0.15 dB. The HDFL is highly stable, with the lasing output have a low power fluctuation of only 2.3 dB over a continuous operation period of 75 min. The proposed HDFL would have substantial applications as a low cost laser source for sensing applications beyond the 2 µm region, particularly those that require a control signal.
