Journal ArticleDOI
Tilted fiber Bragg grating sensors
TL;DR: In this paper, a tilt of the grating fringes causes coupling of the optical power from the core mode into a multitude of cladding modes, each with its own wavevector and mode field shape.
Journal ArticleDOI
Pressure sensor realized with polarization-maintaining photonic crystal fiber-based Sagnac interferometer.

TL;DR: A novel intrinsic fiber optic pressure sensor realized with a polarization-maintaining photonic crystal fiber (PM-PCF) based Sagnac interferometer is proposed and demonstrated experimentally.
Journal ArticleDOI
Fiber-taper seeded long-period grating pair as a highly sensitive refractive-index sensor
TL;DR: In this paper, the fabrication and characterization of a highly sensitive refractive index sensor based on a long-period grating (LPG) pair with a fiber-taper section in between was reported.
Journal ArticleDOI
Sensitivity-enhanced temperature sensor with cascaded fiber optic Sagnac interferometers based on Vernier-effect
TL;DR: In this paper, a novel fiber optic temperature sensor has been proposed and experimentally demonstrated with ~9 times sensitivity enhancement by using two cascaded Sagnac interferometers, which consist of the same type of polarization maintaining fibers with slightly different lengths.
Journal ArticleDOI
High resolution interrogation of tilted fiber grating SPR sensors from polarization properties measurement
TL;DR: The Jones matrix associated to the TFBG transmission properties is measured in order to be able to analyze different polarization-related parameters (i.e. dependency on wavelength of polarization dependent loss and first Stokes parameter) and the maximum error on refractive index measurement has been determined to be 5 times better than intensity-based measurements on the same sensors.
