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."
