AI Technical Summary
In existing technologies, splicing hollow fiber to solid fiber results in high optical loss and high back reflection, especially when mechanically spliced, which is easily affected by environmental pollutants.
By manufacturing an optical fiber using a stack of optical rods made of various materials, heating and stretching them along the longitudinal axis to form the optical fiber, and utilizing the different etching resistance of the materials to create a structured surface on the end face of the optical fiber, the volume average refractive index is controlled to match different optical fibers, thus achieving splicing with low optical return loss.
It effectively reduces optical loss and back reflection at fiber optic splices, improves optical transmission efficiency, and protects optical fibers from environmental pollutants.
