Fibre Bragg grating (FBG) pressure sensors show a great potential in replacing conventional
electrical pressure sensors due to their numerous advantages. However, increasing their …

Fiber optic sensors are expected to be an auxiliary measurement tool in the field of ocean
observation due to their small size, easy networking, intrinsic immunity to electromagnetic …

A miniature fiber-tip pressure sensor was built by using an extremely thin graphene film as
the diaphragm. The graphene also acts as a light reflector, which, in conjunction with the …

A fiber-optic Fabry-Pérot acoustic sensor with a ∼100-\rmnm-thick multilayer graphene
diaphragm is reported. Acoustic testing demonstrates a pressure-induced deflection of 1100 …

We demonstrated a high-sensitivity strain sensor based on an in-fiber Fabry–Perot
interferometer (FPI) with an air cavity, which was created by splicing together two sections of …

We investigated a novel and ultracompact polymer-capped Fabry-Perot interferometer,
which is based on a polymer capped on the endface of a single mode fiber (SMF). The …

A Mach-Zehnder interferometer based on a twin-core fiber was proposed and
experimentally demonstrated for gas pressure measurements. The in-line Mach-Zehnder …

We demonstrate a sub-micron silica diaphragm-based fiber-tip Fabry–Perot interferometer
for pressure sensing applications. The thinnest silica diaphragm, with a thickness of∼ 320 …

We experimentally demonstrated a high sensitive gas pressure sensor, which also has more
concise processing steps and lower cost. The sensor was fabricated by splicing the single …

A high sensitivity optical fiber gas pressure sensor based on the enhanced Vernier effect is
proposed. The sensor is composed of a fiber Fabry-Perot interferometer (FPI) and Mach …
