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

We demonstrated an in-line open cavity Fabry–Perot interferometer (FPI) for liquid refractive index sensing with linear response and high sensitivity. The FPI was fabricated by splicing a short piece of C-shaped fiber (tens of micrometers) between

We report the fabrication and characterization of an in-line photonic crystal fiber optofluidic refractometer assisted by a C-shaped fiber. The C-shaped fiber spliced between the PCF and the SMF enables simultaneous in-line optical signal delivery an

A magnetic field sensor is demonstrated by placing a bent-fiber taper modal interferometer inside a magnetic fluid sealed with an organic glass base. Owing to the strong refractive index dependency of the interferometer and magneto-optics property of

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
