Fig. 6: Polarization-dependence for capacitively-driven Friedrich–Wintgen (FW-) bound states in the continuum (BICs).

From: Polarization-selective modulation of supercavity resonances originating from bound states in the continuum

Fig. 6

a–e Contour plot illustrating the transmission amplitude for different values of the rotation angle ϕ between 0° and and 90°, respectively. The white vertical dashed lines indicate the FW-BIC positions with vanishing linewidth. A standard Jaynes–Cummings Hamiltonian is used here to fit the numerical data. The green (blue) dashed lines represent the dipole (quadrupole) mode transmission dip positions. f Evolution of the normalized coupling strength g/ω0 vs. polarization angle ϕ.
