Miniature multicore optical fiber vibration sensor.

We demonstrate a compact and versatile interferometric vibration sensor that operates in reflection mode. To build the device, a short segment of symmetric strongly coupled multicore optical fiber (MCF) is fusion spliced to a single-mode optical fiber (SMF). One end of the MCF segment is cleaved and placed in a cantilever position. Due to the SMF-MCF configuration, only two supermodes are excit...

Miniature high-sensitivity high-temperature fiber sensor with a dispersion compensation fiber-based interferometer.

A miniature high-sensitivity, high-temperature fiber sensor with an interferometer based on a bare small-core-diameter dispersion compensation fiber (DCF) is reported. The sensing head is a single-mode-fiber (SMF) DCF configuration formed by a 4 mm long bare DCF with one end connected to the SMF by a fusion splicing technique and the other end cleaved. Due to the large mode index difference and...

High Sensitive Temperature Sensor Using a Liquid-core Optical Fiber with Small Refractive Index Difference Between Core and Cladding Materials

An intensive temperature sensor based on a liquid-core optical fiber has been demonstrated for the measuring the temperature of the environment. The core of fiber is filled with a mixture of toluene and chloroform in order to make the refractive index of the liquid-core and the cladding of the fiber close. The experiment shows that a temperature sensitivity of about 5 dB/K and a tunable tempera...

A miniature optical breathing sensor

We demonstrate a novel miniature optical breathing sensor based on an Agarose infiltrated photonic crystal fiber interferometer. The sensor detects the variation in relative humidity that occurs between inhaled and exhaled breath. The sensor interrogation system can determine the breathing pattern in real time and can also predict the breathing rate and the breathing status during respiration. ...

Gas Sensor Based on Large Hollow-Core Photonic Bandgap Fiber

One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...
