Glasses for Optical Fibers and Other Applications
An example of industrial work career for physicist: what are the interesting parts of it, what are the heaviest types of tasks, and how to get through and learn to solve problems and to improve products and production methods; introduction to solid-state materials and their properties; material compositions and manufacturing methods of glasses for various types of products (windows, high strength materials, vessels, glass cover of ceramic materials, glass cover of electronic components, optical fibers); how the recycled glasses are used and their benefits; coloured glasses; glass in optical fibres; coating materials of optical fibers, manufacturing method for optical fibres; communications optical fibres and fiber components and their optical and mechanical properties; history and problems solved in the communications fibres 1976-2020; characterisation and measurement methods for fibers and fiber components; splicing methods and manufacturing of fiber components; specialty optical fibers, fiber lasers and amplifiers; examples of photonics glasses and materials; two visits to industrial companies: a fibre and glass product factory and a photonics material factory; discussions with and short task reports to the students.

Master level students
After completing the course, the student is expected to understand
• how the industrial companies are functioning
• what kind of tasks and challenges physicists perform and face respectively in industry
• where to get help, when you must solve a new problem to which there is no prior solution
• the types of solid-state materials and their properties and differences, including glass
• manufacturing methods of glasses, their material composition and properties, and how the properties depend on the composition and manufacturing process
• ways to make coloured glasses
• optical and photonic properties of glasses, and the measurement methods of them
• the materials in optical fibers, both glass and coatings, and the special properties and manufacturing methods of optical fibers
• the types and properties of communications fibers, the measurement methods and international standards
• the fiber splicing methods and methods to manufacture fiber components (splitters etc.)
• which “childhood” problems optical fibers had in a few tens of years ago, and how the problems were solved out
• about which optical and mechanical reliability problems are possible to appear in fibers, and how to avoid them
• how fiber lasers and amplifiers are manufactured, their properties and other types of specialty optical fibers
• about photonic materials and photonic glasses, which functions are so far available to be made into glasses, and how.
