“…The adjustive range of pump power P p is from 20 mW to 500 mW, and the step is 20 mW. The output power and 3 dB bandwidth are directly measured by the OSA, while the pump conversion efficiency, spectral line width [26] and mean wavelength [1] are respectively obtained by the following three formulas:…”

An Erbium-doped fiber source with a near-Gaussian-shaped spectrum consisting of only a single peak, based on the double-stage energy matching and LPFGs, is proposed and demonstrated. A double-stage Erbium-doped fiber source system is built. The first-stage structure adopts the single-pass forward pumping method with a 15 m Erbium-doped fiber, while the second-stage structure adopts the backward-pumping method with a 26.5 m Erbium-doped fiber. The energy of the output spectrum is concentrated near the long wavelength (1560 nm) through the double-pump energy matching of the two stages. Long period fiber gratings (LPFGs) are used to filter the excess light near the short wavelength (1530 nm) in order to obtain a near-Gaussian-shaped spectrum consisting of only a single peak. The output power, pump conversion efficiency, line width, 3 dB bandwidth and mean wavelength of this near-Gaussian-shaped spectrum are tested and analyzed. When the pump powers of the first and second stages are 50 mW and 360 mW, respectively, the results show that a near-Gaussian-shaped spectrum with a power of 10.17 mW, spectral line width of 19.767 nm, and mean wavelength stability of −0.978 ppm/mW can be obtained. This research provides a method for the generation of a near-Gaussian-shaped spectrum with high output power and excellent mean wavelength stability, and it can produce multiple forms and energies of near-Gaussian-shaped spectra via this Erbium-doped fiber source.

“…The research on Erbium-doped fiber sources have been restricted mostly to a two-peak spectrum [26,27], which, compared with a single-peak spectrum, shows a worse intrinsic mean-wavelength stability [28] and is not conducive to the application of high precision FOG. Additionally, only few works have reported a single-peak spectrum.…”

“…Self-powered sensors typically require long-term use in environments with a strong electromagnetic [12], humidity [13], and high temperature [14]. Energy management circuits, due to their electrical characteristics, may suffer certain harm when used in harsh environments for a long time, thereby reducing the energy conversion efficiency of energy management circuits [15] and making the output power unstable [16]. Poor environments may reduce communication performance such as wireless communication distance [17].…”

The energy harvesters used in self-powered wireless sensing technology, which has the potential to completely solve the power supply problem of the sensing nodes from the source, usually require mechanical movement or operate in harsh environments, resulting in a significant reduction in device lifespan and reliability. Therefore, the influencing factors and failure mechanisms of the operating status of self-powered wireless sensors were analyzed, and an innovative evaluation index system was proposed, which includes 4 primary indexes and 13 secondary indexes, including energy harvesters, energy management circuits, wireless communication units, and sensors. Next, the weights obtained from the subjective analytic hierarchy process (AHP) and objective CRITIC weight method were fused to obtain the weights of each index. A self-powered sensor evaluation scheme (FE-SPS) based on fuzzy comprehensive evaluation was implemented by constructing a fuzzy evaluation model. The advantage of this scheme is that it can determine the current health status of the system based on its output characteristics. Finally, taking vibration energy as an example, the operational status of the self-powered wireless sensors after 200 h of operation was comprehensively evaluated. The experimental results show that the test self-powered wireless sensor had the highest score of “normal”, which is 0.4847, so the evaluation result was “normal”. In this article, a reliability evaluation strategy for self-powered wireless sensor was constructed to ensure the reliable operation of self-powered wireless sensors.
