Observation of Light Emission in Fiber Fuse
Author Information
Author(s): Todoroki Shin-ichi
Primary Institution: National Institute for Materials Science
Hypothesis
The study investigates the relationship between the damage pattern and the propagation mode of optical discharge in fiber fuses.
Conclusion
The light emission pattern corresponds to the void train formed over the splice point, indicating a complex interaction during fiber fuse propagation.
Supporting Evidence
- The study recorded ten examples of fiber-fuse propagation, all showing similar tendencies.
- High-speed videography allowed for detailed observation of the optical discharge and void formation.
- The light emission pattern was found to be related to the void train formed over the splice point.
Takeaway
When a laser hits a fiber, it can create a series of tiny holes, and this study looked at how those holes form and change shape as the laser moves.
Methodology
The study used ultra-high speed videography to capture the light emission and void formation during fiber fuse propagation.
Limitations
The study may not account for all variables affecting fiber fuse behavior in different conditions.
