We report on strong coupling between a discrete optical mode of a high-Q micropillar cavity and single excitons of self assembled In0.43Ga0.57As quantum dots and compare the results with previous studies on In0.3Ga0.7As quantum dots.
Sum frequency data are reported from the nonlinear interaction of two coherently excited resonant modes of a two-dimensional planar photonic crystal microcavity patterned in a free-standing InP slab.
We observed highly non-thermal features from the photoluminescence of InGaAs/GaAs quantum dots in a planar microcavity. The effect was interpreted in terms of the interplay of phonon relaxation and cavity-dependent excitonic radiative recombination.
We report the first realization of a monolithic vertical-cavity, surface emitting micro optical parametric conversion nanostructure, triply resonant with the parametric frequencies, allowing parametric oscillation or amplification with a very low pump power threshold.
Optical microcavity was fabricated in an AlGaAs-based photonic crystal slab. The optical resonance was within the communication wavelengths and had a quality factor of 1900. Optical bistability due to thermo-optic origin was observed.
We modulate cavity-polaritons using surface acoustic waves. The corresponding formation of a mini-Brillouin zone and band folding of the polariton dispersion is demonstrated for the first time. Results are in good agreement with model calculations.
We demonstrate strong-coupling and exciton hybridization in an organic-inorganic microcavity containing InGaP QWs and the small molecular weight organic tetraphenylporphyrin. The hybrid excited state is found to persist up to temperatures of 100 K.
Spatio-temporal dynamics of coherent exciton-polariton populations in semiconductor microcavities shows a rich ultrafast behaviour that presages many of the features of coherent matter condensates. For condensates at room temperature the response is necessarily ultrafast.
We use the finite difference time domain method (FDTD) to investigate polarisation control of single-photon emission from single quantum dots confined in elliptical micro-pillar microcavities. In contrast to circular pillars, one of the cavity modes has smaller modal volume and maintains high Q-factor.
We discuss polariton formation in high-quality stress compensated crack-free A10.13Ga0.87N/A10.56Ga0.44 N microcavities grown by molecular beam epitaxy on thick GaN templates. Microcavity design for studies of the strong coupling regime in GaN will be discussed.
Side-coupled-integrated-spaced-sequence-of-resonators (SCISSORs) with many rings are important for controlling the behavior of light propagation. We show the linear performance of SCISSORs in high index-contrast AlGaAs in 1, 2, 4, and 8 ring configurations.
We demonstrate an efficient source of nearly indistinguishable single photons from an InAs quantum dot coupled to a photonic crystal microcavity. This QD-cavity coupled system has applications in quantum information science.
