  • Hollow-core photonic crystal fiber gas cell and method for preparing the same
    Patent number: 9709730
    Abstract: A hollow-core photonic crystal fiber gas cell and method for preparing the same. The hollow-core photonic crystal fiber gas cell comprises a single-mode fiber, a fiber splicing protection sleeve, a hollow-core photonic crystal fiber, and a photoelectric detector. One end of the single-mode fiber is fusion spliced with one end of the hollow-core photonic crystal fiber to form a fusion splice and seal one end of the hollow-core photonic crystal fiber gas cell. The fiber splicing protection sleeve covers and protects the fusion splice. The other end of the hollow-core photonic crystal fiber is processed into an output end by fusion sealing, and the surface of the output end faces, but is not parallel to, a detection surface of the photoelectric detector.
