نویسندگان
چکیده
Abstract A high-sensitivity temperature sensor based on the harmonic Vernier effect is proposed and verified by experiments. The main component of a Sagnac interferometer consisting two sections polarization maintaining fibers (PMFs) spliced with an intersection angle 45° between their fast axes. achieved setting length one PMFs integral multiple ( i -times) other plus detuning factor. Compared fundamental effect, sensitivity higher, reaching +1 times that order harmonic).

Miniature high-sensitivity high-temperature fiber sensor with a dispersion compensation fiber-based interferometer.
A miniature high-sensitivity, high-temperature fiber sensor with an interferometer based on a bare small-core-diameter dispersion compensation fiber (DCF) is reported. The sensing head is a single-mode-fiber (SMF) DCF configuration formed by a 4 mm long bare DCF with one end connected to the SMF by a fusion splicing technique and the other end cleaved. Due to the large mode index difference and...
متن کاملHighly sensitive refractive index sensor based on two cascaded microfiber knots with vernier effect
A highly sensitive refractive index (RI) sensor based on two cascaded microfiber knots with vernier effect is proposed and demonstrated by theoretical arithmetic. Deriving from high proportional evanescent field of microfiber and sharp spectrum fringes induced by vernier effect, a slight change of ambient RI will cause large variation of effective RI and significant wavelength shift of resonant...

We propose and experimentally demonstrate a refractive index (RI) sensor based on cascaded microfiber knot resonators (CMKRs) with Vernier effect. Deriving from high proportional evanescent field of microfiber and spectrum magnification function of Vernier effect, the RI sensor shows high sensitivity as well as high detection resolution. By using the method named "Drawing-Knotting-Assembling (D...
متن کاملA Novel High-Sensitivity, Low-Power, Liquid Crystal Temperature Sensor
A novel temperature sensor based on nematic liquid crystal permittivity as a sensing magnitude, is presented. This sensor consists of a specific micrometric structure that gives considerable advantages from other previous related liquid crystal (LC) sensors. The analytical study reveals that permittivity change with temperature is introduced in a hyperbolic cosine function, increasing the sensi...
متن کاملHigh Sensitivity Sensor Based on Porous Silicon Waveguide
Porous silicon (PSi) waveguides are fabricated as a new platform for high sensitivity biosensors. Biomolecules infiltrated into the PSi waveguide increase the effective refractive index of the waveguide and change the angle at which incident light couples into a waveguide mode. Due to the high surface area to volume ratio of PSi and the confinement of optical energy in the region where the biom...
