Abstract The Internet-of-Things (IoT) has witnessed exponential growth over the past decade
and will significantly reshape human life from every aspect, eg, defense, environmental …

As a clean and sustainable energy source, hydrogen gas is highly demanded in industrial
and commercial fields. Accordingly, the swift and accurate detection of hydrogen gas is …

Fiber optic devices are being increasingly employed in the fields of chemical and
environmental sensing due to their important features, such as high accuracy, small size …

A safe detection of hydrocarbons is a major concern in industrial and public environment,
due to their high volatility and flammability. In this work, we report the development and …

A simple, compact and highly sensitive hydrogen sensing device based on a polymer-filled
hollow core fiber coated with Pt-loaded WO 3/SiO 2 is demonstrated. The device is …

We introduced a nanopatterned fiber-optic interferometer (FOI) based on an optical fiber line
embedded with a short capillary which excites the evanescent field by total reflection of light …

As decarbonization is urgent in global climate, hydrogen, of which the product is pure water
after burning, becomes a potentially clean and sustainable energy source as a replacement …

Bio-chemical sensors are expected to offer high sensitivity and specificity towards the
detection of an analyte. It has been found that optical sensors based on long period fiber …

A hydrogen sensor based on erbium-doped fiber ring laser with modal interferometer is
proposed. A single mode-multimode-single mode (SMS) modal interferometer structure …

Refractive index (RI) sensing is a promising technique in a variety of different scientific and
industrial applications. In this paper, we theoretically and experimentally propose a newly …
