Course guarantor:

Stanislav Zvánovec

Lecturer:

Matěj Komanec, Stanislav Zvánovec

Tutor:

Jan Šístek

Supervisor:

Synopsis:

The aim of the course is to introduce mechanisms of propagation of optical waves in optical fibers and fiber components. Furthermore, the optical measuring techniques and measuring methods for the characterization of optical fibers will be presented. Lectures include both the design and methodology of measuring transmission parameters for optical communication systems such as numerical aperture, attenuation, dispersion, and measurement of basic characteristics of active and passive elements of optical communication systems - connectors, splices, couplers, refractive indices etc.

Requirements:

An active attendance of seminars together with elaborated laboratory projects to be fulfilled to reach an assessment.

Syllabus of lectures:

1. Basic concepts and definitions, optical fibers

2. Modal structure, evanescent wave, measurement of optical fiber waveguides, excitation conditions, modal filter, measuring of numerical aperture
