The architecture of an all-tunable optical fiber ring resonator is described in detail in this paper. This architecture has been firstly modeled using an original CAD approach. The simulation results demonstrate a total control of both the absolute frequency and the free spectral range of the final optical resonance comb generated by the optical resonator. The different experimental setups used...

use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems is not an accurate approach; because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. in this study, the infiltration parameters were determined under real conditions of a center pivot system. for this purpose, a single ri...

We propose a short period undulator based on the electromagnetic field pattern in THz-driven split ring resonator structure. An analytical model is developed that allows us to assess key performance parameters of and estimate emitted radiation spectrum. Different geometric configurations are compared detail using numerical simulations. A 100 MeV electron bunch with 5 pC charge shown emit narrow...

Abstract Ring resonator is an essential element in silicon integrated circuit, it widely used as filter, wavelength multiplexer and switch single-mode operation regime. As the rapid development of mode division multiplexing (MDM) technique, ring that can process multi-mode signals simultaneously uniformly highly desired. However, severe modal dispersion makes identical transmission for differen...
