Millimeter-wave dynamics and control of Rydberg-Rydberg transitions
… the Doppler broadening enough to allow for coherent manipulation of Rydberg states and a coherent coupling of an optical and millimeter-wave photon. I demonstrate this coherent coupling in an ensemble of barium atoms, and provide a theoretical description of how to provably perform complete …

Vertical Cavity Surface-Emitting Lasers Operating With Multiple Photonic Crystal Defect Cavities
Coherently coupled arrays of vertical cavity surface emitting lasers (VCSELs) offer the potential of extended area coherent sources with high spectral purity, useful in a variety of applications in the high power (laser radar, optical communications, steerable sources) and low power (image …

Brillouin scattering induced transparency and generation of slow and fast light
… from one energy level to another through coherent coupling with a third, intermediate energy level that creates an interference pathway. In this study, Brillouin scattering analogue of EIT is demonstrated using the two optical modes that are coupled through a phase matched acoustic mode. …

Subradiant, superradiant and Fano resonances in dimer and ring/disk nanocavities
… of the hybridized mode due to antisymmetric coupling of the dipole moments of the parent plasmons. We observe the appearance of Fano resonances in the optical response of plasmonic nanocavities due to the coherent coupling between their superradiant and subradiant plasmon modes due to …

Simulation of curved-space quantum field theories with two-component Bose-Einstein condensates: from black-hole physics to cosmology
… condensates, possibly in the presence of a coherent coupling between the two-components: the availability of various branches of elementary excitations with different sound speed and effective mass may in fact lead to advantages in the implementation of interesting geometries and, …

Quantum Semiconductor Structures Dressed with Terahertz Cavity Photons
… in condensed matter cQED, i.e., studies of coherent coupling of solids with cavity photons. Because of the giant dipole moments associated with resonances in solids, compared to atomic dipoles, uncharted regimes of strong and ultrastrong coupling are currently explored in various systems, …

Angle-resolved photoemission studies of quantum-electronic coherence in metallic thin-film systems
… The simulations presented quantify the coherent coupling of the Ag and Pb electronic structures, affording a useful and non-invasive means for accessing deeply buried structures. This demonstrated exploitation of electronic coherence will prove useful to applications requiring the …

Enhanced digital modulation of coherently coupled vertical cavity laser arrays: theory and application
Dynamic properties of coherently coupled 2x1 vertical-cavity surface-emitting laser (VCSEL) arrays have been studied theoretically and experimentally. Directly modulated VCSELs are the dominant digital light source in short-haul data communication links due to their low cost and low operating …

Coherently-driven exciton polaritons and directional cQED effects in the quantum dot-micropillar system
… effort was needed to enter the strong coupling regime of single emitter cQED to study for instance the non-harmonicity of resulting Jaynes-Cummings ladder and to perform quantum non-demolition measurements at the heart of quantum optics. Corresponding milestone experiments paved the way …

Superradiant Emission from Delocalized Frenkel Excitons in Molecular J-Aggregates
Coherent coupling of excitations between chromophores in molecular J-aggregates leads to delocalized Frenkel excitons that span multiple molecules in the aggregate. Delocalized Frenkel excitons in molecular J-aggregates provide an avenue to access high-speed fluorescent materials with unique …

Coherently coupling multiple elements in vertical-cavity surface-emitting laser arrays
… laser (VCSEL) arrays with three or more emitters coherently coupled are the focus of this work. VCSEL arrays have many established applications and reliable coherent VCSEL arrays are a next step in their progression. The key innovation of this work is individual addressability to each array …
