Optical fibres technology

Lecture topics:

Types of silica glass. Technologies used to produce synthetic silica glass. Optical fiber preforms technologies. Optical fiber drawing processes. Optical and mechanical quality assessment of the optical fibers. Introduction to optical materials science (structure of materials, crystalline and amorphous materials, types of bonds). Non-optical physicochemical properties of organic and inorganic materials (mechanical, electrical, thermal, chemical). Division of materials. Optical materials (glass, crystals, liquid crystals, optical ceramics, plastics). Optical and non-optical properties of optical materials. Research methods used in materials science.

E-learning: The entire lecture, prepared in PowerPoint, can be carried out remotely using Teams/Virtual Campus.

Laboratory topics:

Production of thick core fibers (PCS). Preparation of optical fiber preforms and multimode fibers. Measurements of optical fibers mechanical properties. Thermal and spectroscopic analysis of selected granulates used in the production of polymer optical fibers.

E-learning: The lecturer uses the camera to show all the equipment necessary to performe the classes, at the same time tells about the way of using this apparatus. During each laboratory measuring technique (both theory and methodology of calculation) is discussed. To do this, the lecturer use a graphics tablet or other tool that allows students to keep track of the written contents. Classes end with the e-mail sending of numerical data, on the basis of which students must prepare a report, based on the knowledge gained during the present laboratory.

Seminar topics:

Glassy state. Glass - constructions theories, formation conditions and structure. Properties of glass - viscosity, crystallization, mechanical strength, thermal expansion, chemical and electrical properties, additivity of glass properties. Basics of glass technology - raw materials, glass mass melting, products forming, stress relaxation and hardening, other methods of product modification. Optical properties of glasses, optical glasses - manufacturing technology, types and their properties, photochromic glass, optical fibers drawing processes. Ceramic processes: sintering and seeds growth, nucleation and crystallization. Materials used for the production of silica optical fibers - characteristics (types of glasses). Materials used for the production of polymer optical fibers - characteristics. Analytical methods used to analyze materials suitable for polymer and silica optical fibers. Protective coatings. Inorganic and organic dopants and their influence on the materials properties from which optical fibers are made. Mechanical properties of optical fibers and echanical anaylisis. Optical fiber cables. The use of optical fibers in medicine and telecommunications. Fiber optics used as lighting.

E- learning: The lecturer discusses each topic with the students. Students develop the assigned topics and then present their studies during online classes. Then there is a discussion. The tasks are performed individually or in pairs.
