title = "High-quality-factor WG modes in semiconductor microcavity pillars with circular and elliptical cross section",
abstract = "We observed whispering gallery resonances (WGMs) in semiconductor micropillars by employing geometry in which both excitation and collection of emission is in a direction normal to the sidewall surface of the pillars. The spectral positions of the peaks are found to be in a good agreement with the results of numerical modeling performed by finite difference time domain technique. The quality factors of WGMs (Q ∼ 20000 for the 4 - 5 μm circular pillars) are found to be well in excess of Q-factors for the low Q-vector {"}photonic dot{"} states measured from the same pillars. Due to high Q-factors and small modal volumes ∼ 0.3 μm3 such WGM resonances can be used in cavity quantum electrodynamics experiments.",
