    Amplification of nonlinear polariton pulses in waveguides 
    Tapia Rodriguez, Lucy E.; Walker, Paul M.; Sigurdsson, Helgi; Royall, Ben; Farrer, Ian; Ritchie, David A.; Yulin, Alexey V.; Shelykh, Ivan; Skolnick, Maurice S.; Krizhanovskii, Dmitry N. (The Optical Society, 2019-04-03)
    Using a sub-millimeter exciton-polariton waveguide suitable for integrated photonics, we experimentally demonstrate nonlinear modulation of pico-Joule pulses at the same time as amplification sufficient to compensate the system losses. By comparison ...

    Mechanisms of blueshifts in organic polariton condensates 
    Yagafarov, Timur; Sannikov, Denis; Zasedatelev, Anton; Georgiou, Kyriacos; Baranikov, Anton; Kyriienko, Oleksandr; Shelykh, Ivan; Gai, Lizhi; Shen, Zhen; Lidzey, David; Lagoudakis, Pavlos (Springer Science and Business Media LLC, 2020-01-22)
    Bose-Einstein condensates of exciton-polaritons in inorganic semiconductor microcavities are known to possess strong interparticle interactions attributed to their excitonic component. The interactions play a crucial role in the nonlinear dynamics of ...

    Nonlinear polaritons in a monolayer semiconductor coupled to optical bound states in the continuum 
    Kravtsov, Vasily; Khestanova, Ekaterina; Benimetskiy, Fedor A.; Ivanova, Tatiana; Samusev, Anton K.; Sinev, Ivan S.; Pidgayko, Dmitry; Mozharov, Alexey M.; Mukhin, Ivan S.; Lozhkin, Maksim S.; Kapitonov, Yuri V.; Brichkin, Andrey S.; Kulakovskii, Vladimir D.; Shelykh, Ivan; Tartakovskii, Alexander I.; Walker, Paul M.; Skolnick, Maurice S.; Krizhanovskii, Dmitry N.; Iorsh, Ivan V. (Springer Science and Business Media LLC, 2020-04-09)
    Optical bound states in the continuum (BICs) provide a way to engineer very narrow resonances in photonic crystals. The extended interaction time in these systems is particularly promising for the enhancement of nonlinear optical processes and the ...

    Transition from Propagating Polariton Solitons to a Standing Wave Condensate Induced by Interactions 
    Sich, M.; Chana, J. K.; Egorov, O. A.; Sigurdsson, Helgi; Shelykh, Ivan; Skryabin, D. V.; Walker, P. M.; Clarke, E.; Royall, B.; Skolnick, M. S.; Krizhanovskii, D. N. (American Physical Society (APS), 2018-04-19)
    We explore phase transitions of polariton wave packets, first, to a soliton and then to a standing wave polariton condensate in a multimode microwire system, mediated by nonlinear polariton interactions. At low excitation density, we observe ballistic ...
