It is actually found that the highest Q is anticipated with the double-time period asymmetric grating, a element that we explain by the circumstance that the first-get dispersed Bragg resonator (DBR) is recognized for this configuration while, for other configurations, the 2nd-order DBR comes into Engage in. Experiments carried out at telecom wavelengths for all three circumstances working with skinny-movie Al2O3-on-MgF2 waveguides and Ge diffraction gratings show the transmission spectra in qualitative settlement with numerical simulations. For the reason that event of deemed qBIC is often analytically predicted, the outcome acquired may possibly serve as reputable rules for smart engineering of asymmetric grating waveguide couplers enabling really resonant, linear and nonlinear, electromagnetic interactions.
