a–d The real part of the susceptibility of moiré lattices with different twist angles of θ = 0, 16.4°, 27.8° and 54.0° in the forward case. The dash circles mark the injecting position of the probe beam. e–h Simulated output patterns of the forward probe. i, j The real part of the susceptibility and output pattern in the backward case with θ = 27.8° when the backward coupling detuning is Δc′ =−32 MHz. k, l are the same as i, j but with Δc′ = 60 MHz. The amplitudes of the Rabi frequency of the forward moiré and backward Gaussian coupling fields are 165 MHz and 190 MHz, respectively. Δc = 60 MHz and Δp = 68 MHz. The exhibited intensity (I0) of the output pattern in j is artificially enhanced 1022 times to improve its visibility, while the other images show the original intensities.
