Refractive index sensing based on Mach–Zehnder interferometer formed by three cascaded single-mode fiber tapers
TL;DR: A highly sensitive refractive index (RI) sensor based on three cascaded single-mode fiber tapers, in which a weak taper is sandwiched between the two tapers to improve the sensitivity of the sensor.

TL;DR: A highly selective fluorescent probe for Hg2+ that consists of nitrogen doped graphene quantum dots (NGQDs) that are nearly spherical in shape, have an average diameter of 2.7 nm and excitation-independent emission and blue fluorescence is quenched by Hg1+ due to both dynamic and static quenching.
Journal ArticleDOI
Torsion sensing with a fiber ring laser incorporating a pair of rotary long-period fiber gratings
TL;DR: In this paper, a fiber ring laser is used for high-resolution torsion measurement, where the laser cavity consists of a Mach-Zehnder interferometer formed with a pair of long-period fiber gratings written in a twisted single-mode fiber by a CO 2 laser.
Journal ArticleDOI
Tunable dual-wavelength fiber laser with ultra-narrow linewidth based on Rayleigh backscattering
TL;DR: A tunable dual-wavelength fiber laser with a 3dB linewidth of ~700 Hz for each wavelength based on the linEWidth compression mechanism due to Rayleigh backscattering, and the wavelength tuning range is 3nm.
Journal ArticleDOI
Highly sensitive refractive index sensor based on two cascaded special long-period fiber gratings with rotary refractive index modulation
TL;DR: A refractive index (RI) sensor based on a fiber Mach-Zehnder interferometer formed by two cascaded special long-period fiber gratings with rotary refractive Index modulation (RLPFGs), in which the coupling occurred between the guided mode and the high-order asymmetric cladding mode.
