Bragg-enhanced time-domain Brillouin scattering from a propagating acoustic grating
O. S. Ken, D. O. Horiachyi, V. L. Korenev +4
Generation and detection of coherent phonons in semiconductors by femtosecond optical pulses is a powerful tool for high-frequency acoustic control of their electronic properties.…

Digital-Alloy Bragg Mirrors in High-Q Microcavities for Polariton Lasing
V. A. Stolyarov, A. S. Kurdyubov, A. V. Trifonov +7
We present an approach to the molecular-beam epitaxy of high-Q planar GaAs-based microcavities in which the AlGaAs high-index layers of the distributed Bragg reflectors (DBRs) are…

Ultra-small Mode Volume Polariton Condensation via Precision Ion Implantation
Y. C. Balas, X. Zhou, E. Cherotchenko +7
We present a novel method for generating potential landscapes in GaAs microcavities through focused implantation. The ion beam imprints micron-scale patterns of non-radiat…
