It has been demonstrated that the Bragg gratings in a rare-earth doped fiber can be effectively tuned based on the thermal effect induced by the pump absorption. In this letter, we theoretically and experimentally investigate how to improve the optic

We obtain an extremely high current sensitivity by wrapping a section of microfiber on a thin-diameter chromium-nickel wire. Our detected current sensitivity is as high as 220.65 nm/A2 for a structure length of only 35 μm. Such sensitivity is two or

A sensitive Ag+ sensor based on nucleic acid probes modified silica microfiber interferometry is designed and developed. The probes on microfiber surface plays the part on catching Ag+ as tentacles, while their conformation change from random coils t

Surface-plasmon resonance (SPR), which results from the strong sensitivity of the plasmon-propagation constant to the permittivity of a nanoscale layer of material on a metal surface, is an exquisitely sensitive technique to detect chemical and bioch

In this paper, we report a curvature sensor based on an LPG written in an air-clad thin-core fiber (AC-TCF). The achieved curvature sensitivity is −0.226 nm/m−1 with a good linearity with R2 value of 0.991. Unlike conventional LPGs, this AC-TCF L

We report with cladding-carved DBR fiber lasers the responses of beat frequency on external refractive index (RI). Those carves are fabricated by the CO 2 laser milling technique. The device performance with different carve widths and depths are fabr

Tilted fiber Bragg gratings (TFBGs), which eliminate the cross-sensitivity between environmental temperature and fiber deformation, can be designed as highly sensitive biosensors for bio-sample measurements. The miniaturized size together with the ca

Long period gratings (LPGs) inscribed in microfibers have potential applications in wide wavelength-tunable filters, communications, and sensors (e.g., for detection of refractive index and other biochemical parameters). In this work, we propose high

A novel structure, in which a short section of depressed cladding fiber stub containing a Bragg grating is spliced to a single-mode fiber, is proposed in this work. Experimental results, through monitoring the total reflection power from the core and
