--- _id: '4172' abstract: - lang: eng text: "Microdisks made from GaAs with embedded InAs quantum dots are immersed in the liquid crystal 4-cyano-4’-pentylbiphenyl (5CB). The quantum dots serve as emitters feeding the optical modes of the photonic cavity. By changing temperature, the liquid crystal undergoes a phase transition from the isotropic to the nematic state, which can be used\r\nas an effective tuning mechanism of the photonic modes of the cavity. In the nematic state, the uniaxial electrical anisotropy of the liquid crystal molecules can be exploited for orienting the material in an electric field,\r\nthus externally controlling the birefringence of the material. Using this effect, an electric field induced tuning of the modes is achieved. Numerical simulations using the finite-differences time-domain (FDTD) technique\r\nemploying an anisotropic dielectric medium allow to understand the alignment of the liquid crystal molecules on the surface of the microdisk resonator." article_number: '7946' article_type: original author: - first_name: Karoline A. full_name: Piegdon, Karoline A. last_name: Piegdon - first_name: Stefan full_name: Declair, Stefan last_name: Declair - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Heiner full_name: Matthias, Heiner last_name: Matthias - first_name: Martin full_name: Urbanski, Martin last_name: Urbanski - first_name: Heinz-Siegfried full_name: Kitzerow, Heinz-Siegfried id: '254' last_name: Kitzerow - first_name: Dirk full_name: Reuter, Dirk id: '37763' last_name: Reuter - first_name: Andreas D. full_name: Wieck, Andreas D. last_name: Wieck - first_name: Axel full_name: Lorke, Axel last_name: Lorke - first_name: Cedrik full_name: Meier, Cedrik id: '20798' last_name: Meier orcid: https://orcid.org/0000-0002-3787-3572 citation: ama: Piegdon KA, Declair S, Förstner J, et al.
