Applications of the orbital angular momentum (OAM) of light range from the next generation of optical communication systems to optical imaging and optical manipulation of particles. Here we propose a micron-sized semiconductor source that emits light with predefined OAM pairs. This source is based on a polaritonic quantum fluid. We show how in this system modulational instabilities can be controlled and harnessed for the spontaneous formation of OAM pairs not present in the pump laser source…

Polariton pattern formation and photon statistics of the associated emission

We report on the formation of a diverse family of transverse spatial polygon patterns in a microcavity polariton fluid under coherent driving by a blue-detuned pump. Patterns emerge spontaneously

Pattern formation, photonic spin-orbit coupling and topological states in semiconductor microcavities and micropillar lattices

Microcavity polaritons are mixed light-matter quasiparticles arising from the hybridization between confined cavity photons and quantum well excitons. Since their first observation over a quarter of

Vortex avalanche in the perturbed singular beams.

It is revealed that the restored vortex beam has anomalous regions of the OAM spectrum in a form of sharp dips and bursts (resonances) that occur when the integer perturbation parameter coincides with a topological charge of one of the vortex modes.

Doppler effect and micro‐Doppler effect of vortex‐electromagnetic‐wave‐based radar

The vortex electromagnetic (EM) wave carrying orbital angular momentum (OAM) has attracted much attention in radar applications. Aimed at the moving target detection application of vortex EM waves,
