Impedance asymmetry of three-phase supply lines of different conductor profiles and various spaceconfigurations is analysed following to the author`s article published…

This conference paper shows and demonstrates how modern technologies (such as WDM – Wavelength Division Multiplex) were introduced to students of Optical Networks lectured at Brno University of Technology, Faculty of Electrical Engineering and Communication, Dept. of Telecommunications.

We have focused on the investigation of the impact of Ce, Eu, Tm, Eu2O3 and Tm2O3 addition in LPE growth process on the properties of InP layers in the context of their application in detector structures.

The contribution points on relation between sciences and various aspects of the life of a society. The relation of physics and mathematics with technical disciplines is stressed. It is accented that technical education should be based on a mathematical and…

The presented paper is a note on the methodology of measuring the attenuation of ultrasonic waves in the case of observation device not facilitating a direct measurement of the attenuation based on the definition of the ratio of amplitudes. Instead…

A basic description of intermodal interference which follows possibility investigation of intermodal interference in spectral and space region. There is also a brief description of equipments used for such investigation and some illustrations of obtained results. There is pointed in the…

Four-Wave Mixing (FWM) in semiconductor optical amplifiers is an attrative mechanism for wavelenght coversion in wavelenght-division multiplexed (WDM) systems since it provides modulation format and bit rate transparency over wide tuning ranges. A series of systems experiments evaluating several aspects…
