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 …

Microcavity polaritons are light-matter quasiparticles that arise from the strong coupling
between excitons and photons confined in a semiconductor microcavity. They are typically …

We use coupled micropillars etched out of a semiconductor microcavity to engineer a spin-
orbit Hamiltonian for photons and polaritons in a microstructure. The coupling between the …

By exploiting the polarization multistability of polaritons, we show that polarized signals can
be conducted in the plane of a semiconductor microcavity along controlled channels or …

From a theoretical point of view, we discuss a variety of phenomena linked to the spin and
polarization degree of freedom of exciton-polaritons in semiconductor microcavities. We start …

Spin-orbit coupling (SOC) is responsible for a range of spintronic and topological processes
in condensed matter. Here, we show photonic analogs of SOCs in exciton-polaritons and …

We observe the buildup of strong (<? format?>∼<? format?> 50%) spontaneous vector
polarization in emission from a GaN-based polariton laser excited by short optical pulses at …

New effects of polarization multistability and polarization hysteresis in a coherently driven
polariton system in a semiconductor microcavity are predicted and theoretically analyzed …

We observe a spontaneous parity breaking bifurcation to a ferromagnetic state in a spatially
trapped exciton-polariton condensate. At a critical bifurcation density under nonresonant …

Magnetic monopoles are point-like sources of magnetic field, never observed as
fundamental particles. This has triggered the search for monopole analogues in the form of …
