This paper reviews a wide variety of fiber-optic microstructure (FOM) sensors, such as fiber
Bragg grating (FBG) sensors, long-period fiber grating (LPFG) sensors, Fabry-Perot …

A miniature Fabry–Perot (FP) interferometric fiber-optic sensor suitable for high-temperature
sensing is proposed and demonstrated. The sensor head consists of two FP cavities formed …

We report on the fabrication of a monolithic fiber Fabry–Perot interferometer whose cavity is
a microscopic air bubble. The latter is formed when splicing together a conventional single …

Operando monitoring the gas pressure inside the battery continuously during operation is
essential to analyze its charge/discharge characteristics and safety performance. We …

A temperature sensor consisting of cascaded liquid-air cavities based on Vernier effect was
proposed. The cascaded liquid-air cavities were fabricated simply by partially filling a …

A simple method based on Capillary action is proposed to fabricate an optical fiber Fabry-
Perot sensing probe for temperature and humidity measurement. Nafion film serves as the …

The authors deliver a complete overview of fiber-optic Fabry-Perot (FFP) sensing
technology, integrating the knowledge and tools of multiple fields including optics, sensing …

A novel and low cost fiber-optic extrinsic Fabry–Perot interferometer (EFPI) is proposed. The
EFPI is fabricated at the fiber tip by inserting a single mode fiber (SMF) into a partially …

In the present work, a simple temperature fiber laser sensor configuration is proposed. The
temperature fiber laser sensor is based in the combination of a Fabry-Perót hybrid cavity and …

We report a simple and robust all-fiber in-line Fabry-Pérot interferometer (FPI) with an air
bubble cavity, which is fabricated by directly splicing a multimode photonic crystal fiber …
