Q-factor and density of optical modes in pyramidal and cone-shaped GaAs microcavities
M. Karl, T. Beck, S. Li, H. Kalt, and M. Hetterich
GaAs pyramids on top of GaAs/AlAs distributed Bragg reflectors (DBRs) are studied as candidates for microcavities with low mode volume. Photoluminescence spectra of single pyramids with embedded quantum dots show cavity modes with quality (Q-) factors of up to 700. Furthermore, to assess the complex ... [Appl. Phys.
