论文摘要
我们证明了具有基础para-fermi对称性的微孔谐振器阵列的激光。代数的特性允许对传播常数的分析预测和一系列被动谐振器的正常模式，这些谐振器显示了零能量模式的光学模拟，该模式是其自己的手性对。线性模型中的其余正常模式形成手性对，均匀分布在伪零能量模式周围。我们使用此信息来构建B类激光模型，在Para-Fermi代数手学之后，在模式下以不同的强度驱动均匀的位点，以增强或抑制零能模式。零能量模式激光在较大的驾驶比率的初始条件下稳定。用零能量模式抑制的激光是不稳定的，并且更容易受到初始字段配置的影响。
We demonstrate lasing in arrays of microring resonators with underlying para-Fermi symmetry. The properties of the algebra allow the analytic prediction of propagation constants and normal modes of an array of passive resonators that show the optical analogue of a zero-energy mode that is its own chiral pair. The rest of the normal modes in the linear model form chiral pairs that are evenly distributed around the pseudo zero-energy mode. We use this information to construct a class-B laser model where even and odd sites are driven with different strength in a pattern following para-Fermi algebra chirality to demonstrate lasing with enhancement or suppression of the zero-energy mode. Zero-energy mode lasing is stable to initial conditions for a large set of driving ratios. Lasing with zero-energy mode suppression is unstable and more susceptible to initial field configurations.
