Abstract
In this numerical simulation, we study a new optical device based on semiconductor-superconductor structures, showing narrower broadband enhancement of ultrafast two-photon amplification. The modified 2 x 2 transfer matrix method is adopted to calculate the optical proprieties through the multilayered structures for each oblique angle of the incident wave. Frequency-dependent dispersion formula according to the two-fluid Gorter-Casimir theory has been adopted to describe the optical response of incorporated superconductors. The 1D multilayered stacks made of superconductor (GeAs) and Yttrium barium copper oxide (YBCO) are built according to the inflation rule of the quasiperiodic Fibonacci sequence. The designed narrowest filters give resonance-like transmission peaks with a full width at a half maximum of 3.4 nm. The variation of the operating superconductor's temperature, the thicknesses of the hetero-layers, and the longitudinal mechanical strain along the tunable quasi-photonic structure leads to the manipulation of the photonic band gaps and the transmittance resonance peaks. These devices could be attractive for selective drop\pass or pass through wavebands.
