We demonstrate a method to create potential barriers with polarized light beams for polaritons in semiconductor microcavities. The form of the barriers is engineered via the real space shape of a focalized beam on the sample. Their height can be determined by the visibility of the scattering waves generated in a polariton fluid interacting with them. This technique opens up the way to the creation of dynamical potentials and defects of any shape in semiconductor microcavities.

Multivalley engineering in semiconductor microcavities
TLDR
It is shown theoretically that this exciton-photon coupling in semiconductor microcavities in which separate periodic potentials have been embedded for excitons and photons supports degenerate ground-states appearing at non-zero inplane momenta, corresponding to multiple valleys in reciprocal space.
