Title: | Miniaturized fiber in-line Mach–Zehnder interferometer based on inner air cavity for high-temperature sensing | Authors: | Hu, T Wang, Y Liao, C Wang, D |
Issue Date: | 15-Dec-2012 | Source: | Optics letters, 15 Dec. 2012, v. 37, no. 24, p. 5082-5084 | Abstract: | We demonstrate a miniaturized fiber in-line Mach–Zehnder interferometer based on an inner air cavity adjacent to the fiber core for high-temperature sensing. The inner air cavity is fabricated by femtosecond laser micromachining and the fusion splicing technique. Such a device is robust and insensitive to ambient refractive index change, and has high temperature sensitivity of ∼43.2 pm/°C , up to 1000°C, and low cross sensitivity to strain. | Keywords: | Interferometry Temperature Ultrafast lasers |
