Příprava optických vlnovodů ve speciálně navržených Er- a Yb- dotovaných silikátových sklech iontovou výměnou Ag.sup.+./sup./Na.sup.+./sup
Salavcová, Linda ; Ondráček, František ; Míka, M. ; Špirková, J.
Modification of the Ag.sup.+./sup./Na.sup.+./sup. exchange conditions was done in order to decrease optical losses and to modify n(x) profile of the waveguides. This was achieved using reaction melt with decreased Ag.sup.+./sup. content and consequent annealing of the samples.
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.
