Weyl Points and Fermi Arc Surface States in a Self-assemblable Zinc-Blende Photonic Crystal
Johnathon P. Gales, Hengbin Cheng, David J. Pine +1
Colloidal self-assembly has long been proposed as a method for growing large-scale three-dimensional photonic crystals with important optical properties in visible and near-infrare…
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…
Topological Pumping Through a Localized Bulk in a Photonic Hofstadter System
Kyle Linn, Megan Goh, Sachin Vaidya +2
Photonic systems provide a highly tunable platform for emulating quantum Hall physics. This tunability enables probing of the interplay between strong disorder and robust topologic…
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…
Quantized pumping in disordered nonlinear Thouless pumps
Abhijit P. Chaudhari, Marius Jürgensen, Mikael C. Rechtsman
We investigate the dynamics of nonlinear optical Thouless pumps in the presence of disorder, using optical waveguide arrays. It was previously known that the displacement of solito…
