Direct Observation of Topological Edge States in Silicon Photonic Crystals: Spin, Dispersion, and Chiral Routing
Nikhil Parappurath, Filippo Alpeggiani, L. Kuipers +1
Topological protection in photonics offers new prospects for guiding and manipulating classical and quantum information. The mechanism of spin-orbit coupling promises the emergence…
Topological Edge States in Bichromatic Photonic Crystals
F. Alpeggiani, L. Kuipers
Bichromatic photonic crystal structures are based on the coexistence of two different periodicities in the dielectric constant profile. They are realized starting from a photonic c…
Spatial bunching of same-charge polarization singularities in two-dimensional random vector waves
L. De Angelis, F. Alpeggiani, L. Kuipers
Topological singularities are ubiquitous in many areas of physics. Polarization singularities are locations at which an aspect of the polarization ellipse of light becomes undeterm…
A full vectorial mapping of nanophotonic light fields
B. le Feber, J. E. Sipe, M. Wulf +2
Light is a union of electric and magnetic fields, and nowhere is their complex relationship more evident than in the near fields of nanophotonic structures. There, complicated elec…
Electromagnetic helicity in complex media
F. Alpeggiani, K. Y. Bliokh, F. Nori +1
Optical helicity density is usually discussed for monochromatic electromagnetic fields in free space. It plays an important role in the interaction with chiral molecules or nanopar…
