In this paper, a phoxonic crystal structure is designed that shows a complete phononic and photonic ban gap and is capable to guide the optical waves with transverse magnetic polarization and acoustic waves. The materials used in the structure are nylon and molybdenum, which have suitable refractive index and elastic constant. Also, it is worth of noting that the filling factor is 28% for the p...

This paper presents wavelength configurable on-chip solid-state ring lasers fabricated by a single-mask standard lithography. The single- and coupled-ring resonator hosts were fabricated on a fused-silica wafer and filled with 3,3'-Diethyloxacarbocyanine iodide (CY3), Rhodamine 6G (R6G), and 3,3'-Diethylthiadicarbocyanine iodide (CY5)-doped polymer as the reconfigurable gain media. The recorded...

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...

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...
