Integrated photonics
Čtyroký, Jiří
In the lecture for secondary school physics teachers, principles of light propagation in dielectric waveguides are explained. Operation principles of passive, dynamic and active photonic devices, especially components for optical communnication are described, too. Finally, structures with high refractive-index contrast perspective for large-scale photonic integration are mentioned.
Diagnostic of vertically coupled microring resonator
Ondráček, František ; Čtyroký, Jiří ; Skalský, Miroslav
A vertically coupled microring resonator based on Si.sub.3./sub.N.sub.4./sub.-SiO.sub.2./sub. technology was characterized by a tunable sem iconductor laser. The drop spectral responses were measured and resonator finesse, free spectral range and group effective index were determined.
Modelling of optical microresonators
Hubálek, Milan ; Čtyroký, Jiří
The contribution outlines modelling techniques for analysis of microresonator-based integrated optical components. A principle of modelling of the time domain characteristics with the help of the spectral characteristics including influence of nonlinear optic effects is carried out. Results applicable in the field all-optical devices are shown.
