Highly nonlinear trion-polaritons in a monolayer semiconductor
R. P. A. Emmanuele, M. Sich, O. Kyriienko +9
Highly nonlinear optical materials with strong effective photon-photon interactions (Kerr-like nonlinearity) are required in the development of novel quantum sources of light as we…
Spin domains in one-dimensional conservative polariton solitons
M. Sich, L. E. Tapia-Rodriguez, H. Sigurdsson +9
We report stable orthogonally polarised domains in high-density polariton solitons propagating in a semiconductor microcavity wire. This effect arises from spin dependent polariton…
Transition from propagating polariton solitons to a standing wave condensate induced by interactions
M. Sich, J. K. Chana, O. A. Egorov +8
We explore nonlinear transitions of polariton wavepackets, first, to a soliton and then to a standing wave polariton condensate in a multi-mode microwire system. At low polariton d…
Logic Gates with Bright Dissipative Polariton Solitons in Bragg-Cavity Systems
Emiliano Cancellieri, Jasmin K. Chana, Maksym Sich +3
Optical solitons are an ideal platform for the implementation of communication lines, since they can be packed extremely close one to another without risking partial loss of the en…
Exciton-polaritons in van der Waals heterostructures embedded in tunable microcavities
S. Dufferwiel, S. Schwarz, F. Withers +13
Layered materials can be assembled vertically to fabricate a new class of van der Waals (VDW) heterostructures a few atomic layers thick, compatible with a wide range of substrates…
Optical properties of two-dimensional gallium chalcogenide films
O. Del Pozo-Zamudio, S. Schwarz, M. Sich +12
Gallium chalcogenides are promising building blocks for novel van der Waals heterostructures. We report low-temperature micro-photoluminescence (PL) of GaTe and GaSe films with thi…
Two-dimensional metal-chalcogenide films in tunable optical microcavities
S. Schwarz, S. Dufferwiel, P. M. Walker +12
Quasi-two-dimensional (2D) films of layered metal-chalcogenides have attractive optoelectronic properties. However, photonic applications of thin films may be limited owing to weak…
Spatial patterns of dissipative polariton solitons in semiconductor microcavities
J. K. Chana, M. Sich, F. Fras +9
Semiconductor microcavities operating in the polaritonic regime are highly non-linear, high speed systems due to the unique half-light, half-matter nature of polaritons. Here, we r…
The effects of spin-dependent interactions on polarisation of bright polariton solitons
M. Sich, F. Fras, J. K. Chana +10
We report on the spin properties of bright polariton solitons supported by an external pump to compensate losses. We observe robust circularly polarised solitons when a circularly…
Effect of polariton-polariton interactions on the excitation spectrum of a non-equilibrium condensate in a periodic potential
D. N. Krizhanovskii, E. A. Cerda, S. S. Gavrilov +9
Polariton condensates are investigated in periodical potentials created by surface acoustic waves using both resonant and non-resonant optical excitation. Under resonant pumping co…
Effect of the GaAsP shell on optical properties of self-catalyzed GaAs nanowires grown on silicon
O. D. D. Couto, D. Sercombe, J. Puebla +9
We realize growth of self-catalyzed core-shell GaAs/GaAsP nanowires (NWs) on Si substrates using molecular-beam epitaxy. Transmission electron microscopy (TEM) of single GaAs/GaAsP…
Observation of bright polariton solitons in a semiconductor microcavity
M. Sich, D. N. Krizhanovskii, M. S. Skolnick +7
Microcavity polaritons are composite half-light half-matter quasi-particles, which have recently been demonstrated to exhibit rich physical properties, such as non-equilibrium Bose…
Polarization bistability and resultant spin rings in semiconductor microcavities
D. Sarkar, S. S. Gavrilov, M. Sich +7
The transmission of a pump laser resonant with the lower polariton branch of a semiconductor microcavity is shown to be highly dependent on the degree of circular polarization of t…
