All-optical nonlinear phase modulation in open semiconductor microcavities
Fedor A. Benimetskiy, Paul M. Walker, Anthony Ellul +8
We report a significant advancement in ultra low power light-by-light phase modulation using open semiconductor microcavities in the strong light-matter coupling regime. We achieve…
Realization of Z topological photonic insulators made from multilayer transition metal dichalcogenides
Tommi Isoniemi, Paul Bouteyre, Xuerong Hu +5
Monolayers of semiconducting transition metal dichalcogenides (TMDs) have long attracted interest for their intriguing optical and electronic properties. Recently TMDs in their qua…
Exciton-polaritons in GaAsbased slab waveguide photonic crystals
C. E. Whittaker, T. Isoniemi, S. Lovett +8
We report the observation of band gaps for low loss exciton-polaritons propagating outside the light cone in GaAs-based planar waveguides patterned into two-dimensional photonic cr…
Probing and control of guided exciton-polaritons in a 2D semiconductor-integrated slab waveguide
Valeriy I. Kondratyev, Dmitry V. Permyakov, Tatyana V. Ivanova +5
Guided 2D exciton-polaritons, resulting from the strong coupling of excitons in semiconductors with non-radiating waveguide modes, provide an attractive approach towards developing…
Observation of Zitterbewegung in photonic microcavities
Seth Lovett, Paul M. Walker, Alexey Osipov +6
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 pol…
Few-photon all-optical phase rotation in a quantum-well micropillar cavity
Tintu Kuriakose, Paul M. Walker, Toby Dowling +13
Photonic platforms are an excellent setting for quantum technologies because weak photon-environment coupling ensures long coherence times. The second key ingredient for quantum ph…
