AI Article Synopsis
- The study focuses on the significant issue of optical transmittance degradation in tapered fibers, which starts immediately after they are made and can reduce transmittance to nearly zero.
- The research examined how dust particle density and humidity affect this degradation process, finding that dust particles are the primary cause, while humidity has minimal impact.
- In clean environments without dust, the transmittance of tapered fibers can be maintained with very little degradation (less than ±0.02) over a one-week period.
Article Abstract
We investigated the cause of optical transmittance degradation in tapered fibers. Degradation commences immediately after fabrication and it eventually reduces the transmittance to almost zero. It is a major problem that limits applications of tapered fibers. We systematically investigated the effect of the dust-particle density and the humidity on the degradation dynamics. The results clearly show that the degradation is mostly due to dust particles and that it is not related to the humidity. In a dust free environment it is possible to preserve the transmittance with a degradation of less than the noise (±0.02) over 1 week.
