The absorption of electromagnetic energy by a material is a phenomenon that underlies
many applications, including molecular sensing, photocurrent generation and …

Surface plasmons allow electromagnetic fields to be confined to subwavelength scale, well
beyond the classical optical diffraction limit. With continuous reduction of optical mode …

Nearly 30 years ago, two-photon interference was observed, marking the beginning of a
new quantum era. Indeed, two-photon interference has no classical analogue, giving it a …

Metasurfaces based on resonant nanophotonic structures have enabled innovative types of
flat-optics devices that often outperform the capabilities of bulk components, yet these …

Topological photonics has been introduced as a powerful platform for integrated optics,
since it can deal with robust light transport, and be further extended to the quantum world …

On-chip photon sources carrying orbital angular momentum (OAM) are in demand for high-
capacity optical information processing in both classical and quantum regimes. However …

A common wisdom in quantum mechanics is that the Hamiltonian has to be Hermitian in
order to ensure a real eigenvalue spectrum. Yet, parity–time (PT)-symmetric Hamiltonians …

The development of large-scale optical quantum information processing circuits ground on
the stability and reconfigurability enabled by integrated photonics. We demonstrate a …

Photonic quantum information processing, one of the leading platforms for quantum
technologies,,,–, critically relies on optical quantum interference to produce an …

The coupling of photons to collective charge oscillations at the surface of a metal to form
surface-plasmon polaritons enables strong confinement of electromagnetic near fields in the …
