N个紧密间隔的偶极耦合量子发射器的阵列表现出超辐射和亚辐射，具有特征可剪裁的空间辐射图案。优化发射器的几何形状和相对于近共振光学腔模式的空间分布的距离允许我们将光散射到腔模式和自由空间发射之间的比率增加几个数量级。这导致不同的缩放的集体相干发射极场耦合与自由空间衰减作为发射极数量的函数。特别是，对于亚辐射态，有效协同性的增加速度远远超过了独立发射器的典型线性EPN标度。这种非同寻常的集体增强表现在透射光谱中出现在腔输出端口处的窄集体反共振的幅度和相位轮廓中。
An array of N closely spaced dipole coupled quantum emitters exhibits super- and subradiance with characteristic tailorable spatial radiation patterns. Optimizing the emitter geometry and distance with respect to the spatial profile of a near resonant optical cavity mode allows us to increase the ratio between light scattering into the cavity mode and free space emission by several orders of magnitude. This leads to distinct scaling of the collective coherent emitter-field coupling vs the free space decay as a function of the emitter number. In particular, for subradiant states, the effective cooperativity increases much faster than the typical linear ∝N scaling for independent emitters. This extraordinary collective enhancement is manifested both in the amplitude and the phase profile of narrow collective antiresonances appearing at the cavity output port in transmission spectroscopy.
