Abstract: [slo] [eng]
Diplomová práca sa zaoberá popisom základných princípov a vlastností vláknových mriežok s dlhou periódou (LPFGs). Je rozobraný základný matematický popis týchto mriežok, potrebný k ich modelovaniu a simulácii. Následne sú navrhnuté konkrétne modely vedúce ku zmenám tvaru spektra LPFGs, jedná sa o chirpovanie, apodizáciu a zmeny priemerého indexu lomu navg. V prostredí MATLAB sú vytvorené programy slúžiace k napočítavaniu dôležitých parametrov LPFGs a súčasne sú simulované jednotlivé modely vedúce ku zmene tvaru spektra LPFGs. The diploma thesis described the basic principles and characters of the long period fiber gratings (LPFGs). Our concern was to describe basic mathematical description of these gratings needed to their modelation and simulation. Consequently some exact models leading to changes in the shape of the spectrum LPFGs were suggested, these methods were the chirping, apodization and changes in the average refractive index navg. In the Matlab environment, programes for counting the important parametres LPFGs were created and meanwhile each model leading to the change in the shape of the spectrum was simulated.
