Interest in the multiple facets of optical vortices has flourished in the last three decades. This
review examines the basic research and applications of the interplay between optical …

Quantum key distribution—exchanging a random secret key relying on a quantum
mechanical resource—is the core feature of secure quantum networks. Entanglement-based …

Orbital angular momentum (OAM) carried by helical light beams is an unbounded degree of
freedom that offers a promising platform in modern photonics. So far, integrated sources of …

The H1 photonic crystal cavity supports two degenerate dipole modes of orthogonal linear
polarization which could give rise to circularly polarized fields when driven with a π/2 phase …

The quantum dynamics of the electron's spin and orbital angular momenta in semiconductor
quantum rings is analyzed. Both Rashba and Dresselhaus spin-orbit interactions (SOIs) in …

In this study, we examine a photonic wire waveguide embedded with an ensemble of
quantum dots (QDs) that directionally emits into the waveguide depending on the spin state …

Semiconductor microcavities, defined by a planar Fabry-Perot cavity embedding a quantum
well, allow tightly confining both optical and electronic excitations. In these heterostructures …

We report a method to generate angularly polarized vector beams with a topological charge
of one by rotating air holes to form two-dimensional photonic crystal (PC) cavities. The mode …

Photonic crystals have become a very common and powerful concept in optics since its
introduction in the 1980s by Eli Yablonovitch and Sajeev John. It is in fact a concept …

We revisit the surface plasmon resonances established along a planar interface lying
between a lossless dielectric and a lossy metal. By examining the orbital and spin parts of …
