Topic: Fused Silica Step Index Fibers – Advanced Preform and Fiber Metrology
Date: Tuesday, December 10, 2024 at 6:30 PM - 7:30 PM CET
Abstract
This webinar deals with advanced preform and fiber measurement techniques for specialty fibers, with a particular focus on fibers produced using the POD (Plasma Outside Deposition) process. In this process, fluorine-doped fused silica is applied to the outside of a high-purity core rod made of synthetic quartz glass to produce the refractive index step required for the light guiding. Depending on the specific application wavelengths of these specialty fibers, various synthetic fused silica materials are available as core materials, which enable the production of specialty fiber preforms tailored to the application.
The session will begin with a brief introduction to the manufacturing process and typical applications of specialty fibers, followed by an in-depth examination of the characterization of the preforms and the resulting fibers. Key analytical techniques, such as the refractive index profile analysis and the determination of crucial geometric parameters such as ovality and bow in preforms, will be discussed. The characterization of attenuation, the deterioration of fiber transmission induced by high-energy UV light (solarization) and focal ratio degradation (an undesirable broadening of the beam profile in fibers) are examined in more detail.
Particular attention will be paid to the metrological challenges that arise during product characterization. Participants will gain insights into state-of-the-art measurement technologies and methods that are key to the precise development and implementation of specialty fibers for advanced applications. The goal of the webinar is to provide a comprehensive understanding of the metrology required to evaluate and improve the performance and quality of specialty fiber preforms.
