Nonlinear Fano resonance in the spectral vicinity of BIC 1 and BIC 2 at different angles of incidence, θ for I0 = 8.(3) MW/cm2. Blue circles - numerical results by Fourier-Chebyshev pseudospectral method, thick gray line - stable CMT solution, thin dash red line - unstable CMT solution, dash-dot black line - Fano line-shape unperturbed by the nonlinearity.
