“…The reference signal at wavelength 1586.7 nm was used for temperature compensation of the two sensing wavelengths at 1551.5 nm and 1616.3 nm, with the wavelength difference being monitored [72]. Low-birefringence (low-Bi) PCFs with birefringence one or two orders lower than PM-PCFs were also exploited to achieve broader strain sensing range with similar strain sensitivity and a need for temperature compensation due to higher temperature sensitivity [73].…”

Photonic crystal fibers (PCFs), also known as microstructured optical fibers, are a highlighted invention of optical fiber technology which have unveiled a new domain of manipulating light in engineered fiber waveguides with unparalleled flexibility and controllability. Since the report of the first fabricated PCF in 1996, research in PCFs has resulted in numerous explorations, development and commercialization of PCF-based technologies and applications. PCFs contain axially aligned air channels which provide a large degree of freedom in design to achieve a variety of peculiar properties; numerous PCF-based sensors have been proposed, developed and demonstrated for a broad range of sensing applications. In this chapter, we will review the field of research on design, development and experimental achievement of PCF-based interferometric sensors for physical and biomedical sensing applications.

“…An FLM can be made by inserting a highly birefringent (HiBi) fiber, a pressure-induced birefringent single-mode fiber, or a lowly birefringent fiber. Various kinds of FLM-based sensors have been demonstrated [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. In this paper, a brief overview of the recent progress of FLM-based sensors in China Jiliang University is presented.…”

“…Unlike conventional PMFs (bowtie, elliptical core, or Panda), which contain at least two different glasses each with a different thermal expansion coefficient, thereby causing the polarization of the propagation wave to vary with changing temperature, the PCF birefringence is highly insensitive to temperature because it is made of only one material (and air holes). Recently, some of FLMs used PCFs have been developed and applied on various devices [20][21][22] and optical fiber sensors [24][25][26][27][28][29][30][31][32][33][34][35], including strain sensors, pressure sensors, temperature sensors and curvature sensors, and so on. In this chapter, we will first introduce the basic operation principle of FLMs, secondly, will demonstrate a temperature-insensitive interferometer based on a HiBi-PCF FLM.…”
