Observation of Zitterbewegung in photonic microcavities

Autor: Lovett, Seth, Walker, Paul M., Osipov, Alexey, Yulin, Alexey, Naik, Pooja Uday, Whittaker, Charles E., Shelykh, Ivan A., Skolnick, Maurice S., Krizhanovskii, Dmitry N.

We present and experimentally study the effects of the photonic spin-orbit coupling on real space propagetion of polariton wavepackets in planar semiconductor microcavities and polaritonic analogs of graphene. In particular, we demonstrate the appear

Polariton lasing in AlGaN microring with GaN/AlGaN quantum wells

Autor: Delphan, Anthonin, Makhonin, Maxim N., Isoniemi, Tommi, Walker, Paul M., Skolnick, Maurice S., Krizhanovskii, Dmitry N., Skryabin, Dmitry V., Carlin, Jean-François, Grandjean, Nicolas, Butté, Raphaël

Microcavity polaritons are strongly interacting hybrid light-matter quasiparticles, which are promising for the development of novel light sources and active photonic devices. Here, we report polariton lasing in the UV spectral range in microring res

Few-photon all-optical phase rotation in a quantum-well micropillar cavity

Autor: Kuriakose, Tintu, Walker, Paul M., Dowling, Toby, Kyriienko, Oleksandr, Shelykh, Ivan A., St-Jean, Phillipe, Zambon, Nicola Carlon, Lemaître, Aristide, Sagnes, Isabelle, Legratiet, Luc, Harouri, Abdelmounaim, Ravets, Sylvain, Skolnick, Maurice S., Amo, Alberto, Bloch, Jacqueline, Krizhanovskii, Dmitry N.

Photonic platforms are an excellent setting for quantum technologies because weak photon-environment coupling ensures long coherence times. The second key ingredient for quantum photonics is interactions between photons, which can be provided by opti

Ultrafast-nonlinear ultraviolet pulse modulation in an AlInGaN polariton waveguide operating up to room temperature

Autor: Di Paola, Davide Maria, Walker, Paul M., Emmanuele, Ruggero P. A., Yulin, Alexey V., Ciers, Joachim, Zaidi, Zaffar, Carlin, Jean-François, Grandjean, Nicolas, Shelykh, Ivan, Skolnick, Maurice S., Butté, R., Krizhanovskii, Dmitry N.

Publikováno v: Nat. Commun. 12, 3504 (2021)

Ultrafast nonlinear photonics enables a host of applications in advanced on-chip spectroscopy and information processing. These rely on a strong intensity dependent (nonlinear) refractive index capable of modulating optical pulses on sub-picosecond t
