Problems solved by technology
[0005] Although some progress has been made in the research of interferometric micro-nano optical fiber sensors, the existing interferometric micro-nano optical fiber sensors generally need to be welded by two micro-nano optical fibers. Little work has been done on fiber optic sensing with very limited results

An optical fiber sensor provided by the present invention comprises a first optical fiber part, a second optical fiber part and a tapering part which are different parts of a same micro-nano optical fiber, wherein the tapering part is located between the first optical fiber part and the second optical fiber part and comprises a micro-nano optical fiber cladding layer and an optical fiber microcavity structure formed inside the micro-nano optical fiber cladding layer, the optical fiber microcavity structure is along an extension direction of the tapering part, and the two ends of the optical fiber microcavity structure align at the fiber cores of the first and second optical fiber parts respectively. Moreover, the tapering part also comprises at least one microfluid channel, and the microfluid channel is communicated with the optical fiber microcavity structure and extends to the outer surface of the micro-nano optical fiber cladding layer. The present invention also provides a manufacturing method of the optical fiber sensor.
Description
technical field [0001] The invention relates to optical fiber detection technology, in particular to an optical fiber sensor and a manufacturing method thereof. Background technique [0002] Due to the advantages of small size, light weight, corrosion resistance, strong anti-electromagnetic interference ability and easy distributed multi-parameter simultaneous measurement, fiber optic sensors are widely used in aerospace, petroleum, chemical, electric power and many other fields. Integration, intelligence, and networking are the development trends of fiber optic sensors, and high performance and miniaturization are the basis for the above trends of fiber optic sensors. [0003] For example, in the field of biomedicine, it is necessary to use optical fiber sensing probes with high sensitivity and small size to perform minimally invasive detection of tiny or difficult-to-measure parts (such as blood vessels, skulls, etc.). In the field of aerospace, generally hundreds of fibe...
