“…In previous studies on high-Q cavities the very good convergence properties of the method have been demonstrated, and the obtained values (λ 0 , Q) have been confirme by simulations of transmission spectra of light incident to the cavities [15,16]. Accurate results on high-Q cavity properties are obtained in computation times between few seconds and few minutes on standard workstations [16].…”

High-quality cavities in hybrid material systems have various interesting applications. We perform a comprehensive modeling comparison on such a design, where confinemen in the III-V material is provided by gradual photonic crystal tuning, a recently proposed method offering strong resonances. The III-V cavity couples to an underlying silicon waveguide. We report on the device properties using four simulation methods: finite-di ference time-domain (FDTD), finite-elemen method (FEM), bidirectional eigenmode propagation (BEP) and aperiodic rigorous coupled wave analysis (aRCWA). We explain the major confinemen and coupling effects, consistent with the simulation results. E.g. for strong waveguide coupling, we fin quantitative discrepancies between the methods, which establishes the proposed high-index-contrast, lossy, 3D structure as a challenging modeling benchmark.

“…We expect that radiation losses to the sourrounding air limit high-Q performance in this case. 8 For evaluating numerical errors of high-Q resonance simulations using the resonance mode solver we again show a numerical convergence study: The the geometry setting is fixed to to N i = 13, N o = 5. Finite-element polynomial degree p is varied between p = 1 and p = 5, and Q-factor, resonance wavelength and numerical effort are recorded.…”

“…In this field JCMsuite is mainly used to investigate devices like high-Q resonators, waveguide couplers, splitters, or add-drop filters. 20,[110][111][112][113] 3.9 Photonic crystals Photonic crystals are materials with periodic arrangements of the refractive index. The specific (periodic or quasi-periodic) arrangements can lead to special properties like the opening of photonic band-gaps.…”
