DOI: 10.1063/1.4997026
Abstract: We observe lasing emission from an organic microcavity structure at room temperature with a sunflower-like pattern closely resembling Laguerre-Gauss modes. Simultaneously, measured angle-resolved emission spectra below and above the lasing threshold demonstrate the coexistence of… read more here.

DOI: 10.1073/pnas.2014017117
Abstract: Significance Nanoscale dielectric devices are capable of mediating long-range atom–atom interactions using guided mode photons, as well as long-range photon–photon interactions mediated by lattices of atoms. Such systems have the potential to provide new tools… read more here.

DOI: 10.18287/2412-6179-2019-43-4-567-576
Abstract: We performed a comparative numerical study of the conservation of properties of individual Laguerre-Gauss beams and their superpositions in a random environment. The simulation is based on the extended Huygens-Fresnel principle. Studies have shown that… read more here.
