Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

A singlemode-multimode-singlemode (SMS) fiber structure consists of a short section of
multimode fiber fusion-spliced between two SMS fibers. The mechanism underpinning the …

In recent years, optical fiber sensors based on multimode interference (MMI) have attracted
increasing interest and developed into various sensors used in many practical applications …

Magnetic field sensing is an important issue for many application areas, such as in the
military, industry and navigation. The current sensors used to monitor this parameter can be …

Micro-/nanofibers (MNFs) are optical fibers with diameters close to or below the wavelength
of the guided light. These tiny fibers can offer engineerable waveguiding properties …

Micro/nanofibres (MNFs) are optical fibres with diameters close to or below the vacuum
wavelength of visible or near-infrared light. Due to its wavelength-or sub-wavelength scale …

We review the method of producing adiabatic optical micro-and nanofibers using a
hydrogen/oxygen flame brushing technique. The flame is scanned along the fiber, which is …

We demonstrate a nonadiabatic microfiber sensor with a taper diameter of few micrometers.
The modal interference caused by the abrupt taper results in a sinusoidal spectral response …

The proposed sensing device relies on the self-imaging effect that occurs in a pure silica
multimode fiber (coreless MMF) section of a single-mode–multimode–single-mode (SMS) …

Fiber-optic interferometric sensors (FOISs) are widely used in seismometers, hydrophones,
and gyroscopes. The arctangent approach of phase-generated carrier (PGC-Arctan) …
