Název v původním jazyce

Theoretical study of optical switching in multiple core nonlinear microstructured optical fibers

Popis výsledku v původním jazyce

In this study, several approaches to optical switching in multiple core nonlinear microstructured optical fibers are presented. All approaches are based on coupling between the cores of a fiber. Based on Kerr effect, coupling is tuned and detuned by theswitching signal. The propagation constants and field distributions are calculated using our in-house fullvectorial finite element mode solver. Copropagation of the signals at the switching and data wavelengths in a multiple core microstructured opticalfiber is analyzed using the finite element beam propagation method and coupled mode theory. The crucial factor for successful implementation is the fabrication tolerance. Therefore, the dependence of the coupling efficiency on geometry tolerances is alsoanalyzed. From these inaccuracies, the necessary coupling strength and consequently the switching power are deduced. It is shown that for an accuracy of about 2%, the necessary switching power is approximately 26 W in chalcogenide glass
