Extreme sensitivity of nonlinear trajectories enhances optical spectral broadening
Jiachen Wang, Koorosh Sadri, Mikael C. Rechtsman
The generation of a wide spectrum of light in highly nonlinear optical fibers has broad application in spectroscopy, microscopy and medical imaging. To generate such a 'supercontin…

Hyperuniform Disorder in Photonic Crystal Slabs with Intrinsic non-Hermiticity
Zeyu Zhang, Koorosh Sadri, Brian Gould +1
Hyperuniform disorder is a type of correlated disorder characterized by vanishing spectral density at small wavevectors, making the configuration effectively homogeneous on long le…

Stealthy-Hyperuniform Wave Dynamics in Two-Dimensional Photonic Crystals
Maria Barsukova, Zeyu Zhang, Brian Gould +5
Hyperuniform structures are spatial patterns whose fluctuations disappear on long length scales, making them effectively homogeneous when observed from afar. Mathematically, this m…
