Extreme sensitivity of nonlinear trajectories enhances optical spectral broadening
Jiachen Wang, Koorosh Sadri, Mikael C. Rechtsman
The paper demonstrates that a waveguide made of multiple coupled cores (a photonic molecule) produces stronger self‑phase modulation and broader supercontinuum spectra than a singl…
Quantum Geometry in the Continuum: Solitons in Shallow Lattices
Koorosh Sadri, Mikael C. Rechtsman
The quantum geometry of electronic, photonic, and atomic lattice systems quantifies the distance in Hilbert space between Bloch states at neighboring lattice momenta. This quantity…
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…
