Fig. 3: Measured scattering signal from ion arrays.
From: Long-range cooperative resonances in rare-earth ion arrays inside photonic resonators
a Normalized scattering data for the ordered ion arrays (blue) and disordered (randomly distributed) arrays (yellow) as a function of resonant pump wavelength. The scattering from the array near the atomic resonance (~795 nm) shows an enhancement of about 60% for the ordered array compared to the disordered one. The gray curve shows the calculated Bragg resonance that results from the ion implantation process (see text); b A zoomed-in scattering data near-atomic resonance shows modulation of the scattering signal with a period of λ/Ms, where Ms = 1750 is the number of ion segments in the array. The periodic oscillation is in agreement with the model of sinusoidal oscillation (solid line) with a double-peak Gaussian envelope of center and width corresponding to that of the disordered array (total width) data in a. The shaded regions indicate the predicted cavity resonances based on measurement of the cavity spectrum obtained from a different experiment run while taking into the account the uncertainty due to the drift in the cavity resonances. The dashed lines in both plots are guide to the eye.
