Bloch oscillations are a phenomenon well known from quantum mechanics where electrons in a lattice experience an oscillatory motion in the presence of an electric field gradient. Here, the authors report on Bloch oscillations of hybrid light−matter particles, called exciton‐polaritons (polaritons), being confined in an array of coupled microcavity waveguides. To this end, the waveguide widths and their mutual couplings are carefully designed such that a constant energy gradient is induced… 

Observation of the Wannier-Stark ladder in plasmonic waveguide arrays

Evanescently coupled waveguides are a powerful platform to study and visualize the wave dynamics in tight-binding systems. Here, we investigate the propagation of surface plasmon polaritons in arrays

Chaotic Bloch oscillations in driven-dissipative systems

It is shown that the efficiency of the excitation of Bloch oscillations depends not only on the carrier frequency, but also on the frequency of the amplitude oscillations of the driving force. In the

The experimental observation of discrete diffraction and Bloch oscillations of surface plAsmon polaritons in evanescently coupled plasmonic waveguide arrays is reported.

Bloch oscillations of an exciton-polariton Bose-Einstein condensate

We study theoretically Bloch oscillations of half-matter, half-light quasiparticles: exciton-polaritons. We propose an original structure for the observation of this phenomenon despite the

We analyze theoretically the spin dynamics of exciton-polaritons and photons during their Bloch oscillations in a wire-shaped microcavity. The reduced system dimensionality induces a specific

Optical Bloch Oscillations in Temperature Tuned Waveguide Arrays

We report the observation of optical Bloch oscillations in waveguide arrays. The required linear variation of the propagation constant across the thermo-optic polymer array was obtained by applying a

Collective fluid dynamics of a polariton condensate in a semiconductor microcavity

Using a coherent excitation triggered by a short optical pulse, a macroscopically degenerate state of polaritons are created that can be made to collide with a variety of defects present in the microcavity and opens the way to the investigation of new phenomenology of out-of-equilibrium condensates.

The effective potential was measured for various condensate densities and trap geometries, yielding good qualitative agreement with theoretical calculations.

Impact of the Energetic Landscape on Polariton Condensates' Propagation along a Coupler

Polariton condensates' propagation is strongly dependent on the particular energy landscape the particles are moving upon, in which the geometry of the pathway laid for their movement plays a crucial

Observation of bright solitons in a semiconductor microcavity

Microcavity polaritons are composite half-light half-matter quasiparticles, which have recently been demonstrated to exhibit rich physical properties, such as non-equilibrium condensation, parametric

Observation and Uses of Position-Space Bloch Oscillations in an Ultracold Gas.

Two unique capabilities enabled by tracking of Bloch dynamics in position space are demonstrated: measurement of the full position-momentum phase-space evolution during a Bloch cycle, and direct imaging of the lattice band structure.

Using an interacting Bose gas of exciton-polaritons in a semiconductor microcavity, the transition from superfluidity to the hydrodynamic formation of oblique dark solitons and vortex streets in the wake of a potential barrier is reported.
