All-optical beam steering using the polariton lighthouse effect
Samuel M. H. Luk, Hadrien Vergnet, Ombline Lafont +9
We demonstrate theoretically and experimentally that a specifically designed microcavity driven in the optical parametric oscillation regime exhibits lighthouse-like emission, i.e.…
Directional optical switching and transistor functionality using optical parametric oscillation in a spinor polariton fluid
Przemyslaw Lewandowski, Samuel M. H. Luk, Chris K. P. Chan +4
Over the past decade, spontaneously emerging patterns in the density of polaritons in semiconductor microcavities were found to be a promising candidate for all-optical switching.…
Optically controlled orbital angular momentum generation in a polaritonic quantum fluid
Samuel M. H. Luk, Nai-Hang Kwong, Przemyslaw Lewandowski +2
Applications of the orbital angular momentum (OAM) of light range from the next generation of optical communication systems to optical imaging and optical manipulation of particles…
Experimental realization of a polariton beam amplifier
Dominik Niemietz, Johannes Schmutzler, Przemyslaw Lewandowski +8
In this report we demonstrate a novel concept for a planar cavity polariton beam amplifier using non-resonant excitation. In contrast to resonant excitation schemes, background car…
Polarization dependence of nonlinear wave mixing of spinor polaritons in semiconductor microcavities
Przemyslaw Lewandowski, Ombline Lafont, Emmanuel Baudin +11
The pseudo-spin dynamics of propagating exciton-polaritons in semiconductor microcavities are known to be strongly influenced by TE-TM splitting. As a vivid consequence, in the Ray…
All-optical flow control of a polariton condensate using non-resonant excitation
Johannes Schmutzler, Przemyslaw Lewandowski, Marc Aßmann +6
The precise adjustment of the polariton condensate flow under incoherent excitation conditions is an indispensable prerequisite for polariton-based logic gate operations. In this r…
Transverse optical instability patterns in semiconductor microcavities: polariton scattering and low-intensity all-optical switching
M. H. Luk, Y. C. Tse, N. H. Kwong +4
We present a detailed theoretical study of transverse exciton-polariton patterns in semiconductor quantum-well microcavities. These patterns are initiated by directional instabilit…
