To achieve data-driven intelligence in engineering applications, the key requirements for distributed optical fiber sensor networks are large capacity, long distance, dense distribution, fast respo…
The photosensitive behaviors in laser grating formation is an important guideline for the preparation of drawing tower gratings (DTGs) in different optical fibers. We conducted static single-pulse …
A highly sensitive vibration frequency and acceleration sensor is demonstrated, using a liquid-filled photonic crystal fiber. The designed fiber has a unique structure that a central air-bore of mi…
Internal tensile stress inside fiber core can impact significantly on formation of Draw-tower gratings (DTGs). We carry out online dynamic preparation experiments of DTG to analyze the effect of in…
