“…When SMF bends, electromagnetic radiation is ejected from the core and setup a whispering gallery (WG) mode which propagates in the cladding. Then the WG mode light couples back into the core and interferes with the guided core mode, as shown in Figure1 [8][9].…”

Some single-mode fiber and its elements are used in low-polarization and polarization-maintaining hybrid path of fiber optic gyroscope. As the development of the miniaturization of interferometric fiber gyroscope, in some cases during the fiber optic gyroscope (FOG) light path assemble, the bending radius of optical device pigtails has to be bend with a small radius because of the compact structure requirement, particularly in single-mode pigtails. In single-mode optical fiber, the transmitted core-guided mode light and whispering gallery mode light will interfere with each other, and present influence on the transmitted light. In the precious investigations, the wavelength is fixed to 1550nm to measure the power loss with different bending radius of single-mode fiber. Thus, in this paper, a three-in-one integrated light source with the wavelength 1310nm is used for the investigation. The effect of single-mode fiber with bending radius from 4mm to 20mm and winding number from 10-50 will be investigated. It shows that single-mode fiber bending can lead to the transmitted light mean wavelength drifting and oscillating as the temperature ramping.

“…The whispering gallery phenomenon refers to the observations that sonorous vibrations have a tendency to cling to a concave surface [3]. The microbent optical fiber-induced WGM is sensitive to the outside changes and can be adopted as the optic fiber sensor [4][5][6][7][8] and the edge filter [9][10][11]. There are a variety of applications for WGM in bent optical fiber.…”

“…Subsequently, Raikar et al further demonstrated the relationship between the single-mode fiber bending loss and temperatures. They discovered that if the bending angle was increased, the transmission loss of the optical fiber became more severe [7]. More recently, Wang et al demonstrated that two photodiodes could be placed at both ends of a slightly bent optical fiber to measure the output power and to use the translation platform displacement to adjust the bending losses, which formed a simple power measurement system [8].…”

In this study, we demonstrated an edge filter-based fiber Bragg grating (FBG) intensity modulation system to realize strain measurement. In order to establish a precise and highly sensitive intensity modulation system, we utilized a bent single-mode fiber to induce whispering gallery mode (WGM) interference as an edge filter and combined that with a FBG sensor. The interference spectra of the attenuation band for the WGM edge filter were tuned by adjusting the bending radii. In addition, we compared and analyzed the signals from the proposed vibration interrogating system and a strain gauge. The measured voltage signals from the proposed interrogation system were in close agreement with measured strains of the strain gauge. The experimental results showed that when the resonant wavelength of the WGM edge filter was 1535.10 nm, the filtration was better and the noise was lower within 100 Hz. Moreover, as the frequency of piezoelectric transducer (PZT) was at 400 and 1000 Hz, the better signal-to-noise ratios (SNRs) of 28.54 and 25.97 were measured at wavelength 1542.05 nm of the edge filter.
