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.

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…

This contribution summarizes some of the major trends, as well as real opportunities for the application of system fault diagnosis and reconfiguration control structures in automatic control systems. There are referenced ongoing concepts for residual generation, described design approaches in virtual reconfiguration…
