Discussion Overview
The discussion revolves around the challenges of coupling light into a hollow core photonic crystal fiber, specifically focusing on the parameters of the fiber and the laser used. Participants are exploring the reasons for low power transmission and seeking suggestions for improvement.
Discussion Character
- Technical explanation
- Debate/contested
Main Points Raised
- One participant describes their hollow core fiber with a core diameter of 20µm and a Numerical Aperture of 0.03, noting a low power output of 6µW when using a Ti:Sapphire laser.
- Another participant requests additional information about the fiber, questioning whether it is a 7 or 19 cell design, suggesting that the core size may be unusually large for the wavelength in question.
- A participant expresses uncertainty about the fiber's design, indicating it was produced by a different research group.
- Further inquiries are made regarding the cross-section of the fiber and the loss characteristics at the laser wavelength to better understand the coupling issue.
Areas of Agreement / Disagreement
Participants are collaboratively seeking information and suggestions, but there is no consensus on the specific design or characteristics of the fiber, nor on the reasons for the low power output.
Contextual Notes
Limitations include the lack of detailed specifications about the fiber's design and loss characteristics, which may be critical for diagnosing the coupling issue.
It is made by some other research group.
