Label-free fiber optical biosensor has a promising prospect in “point-of-care” (POC) test for disease diagnosis. A sensitive label-free fiber-optic based immunosensor for quantitative Cardiac Troponin I (cTn-I) testing has been proposed by using

We have developed a chip-scale optofluidic sensor for biomolecular detection, by tapering laterally aligned silica microfiber and capillary to form a modal interferometer. With the pre-immobilization of DNA probes, the sensor is capable of selectivel

In this paper, an abnormal grating evolution was recorded during microfiber Bragg grating (mFBG) inscription under 193nm excimer laser. Within 20 minutes exposing, a Type IIa FBG could be obtained with above 20dB strength in 8.5 μm microfiber. This

We realize a microdroplet-etched fiber Fabry-Perot resonator. Strong polarization discrimination is achieved due to the asymmetric fiber cross section in the cavity, which should be useful for improving the measurement precision in the refractive ind

We demonstrate an acid-based sensor from the biofuncationalized microfiber Bragg grating. By electrostatic selfassembly layer-by-layer technique, the film consisting of sodium alginate which has hygroscopic response to the potential of hydrogen is co

A highly-birefringent elliptic microfiber is fabricated by use of the CO2-laser machining and fusion tapering methods. The fiber ellipse can be well controlled with modification of the CO2 laser output power. Both positive and negative sensitivities

Microfiber Bragg gratings (mFBGs) can be used as cost-effective and relatively simple-to-implement biosensors for monitoring DNA interactions in situ. The sensors are functionalized by a monolayer of poly-L-lysine (PLL) with the specific molecular re

We demonstrated a highly sensitive evanescent-wave-based water salinity sensor using a rectangular optical microfiber Sagnac interferometer. The microfiber has a rectangular cross-section with widths of 4.0 μm by 2.5 μm and total length of 36 mm. F

A Mach-Zehnder interferometer (MZI) based on a pair of long period gratings (LPGs) fabricated by silica microfiber for sensing applications is demonstrated. Each LPG with only 6 deformations was fabricated by using a pulsed CO2 laser to periodically

High current sensitivity is obtained based on a microfiber that is wrapping around a chrome-nickel (CrNi) wire. Due to the strong heating effect of the CrNi wire with the flowing electric current, the mode index and the loop length of microfiber are
