We are very pleased to announce and cordially invite you to our monthly EPFL Photonics Chapter (EPC) 'Pizza-optics-beer' (POB) seminar on March 8th, 2017 (Wednesday) at 18h (6pm). The seminar will take place in the room CM 1100.
This month we will have the pleasure to host Albert Adiyatullin who will give us some insights in his field of expertise. His presentation is entitled: “Towards squeezed light generation in a polariton Josephson junction”. Albert and us, we would be happy to see you there!
For organizational purposes (if you want to eat pizza!), please confirm your participation using the following Doodle.
Abstract: Microcavity polaritons are hybrid light-matter quasiparticles that are easily accessible by optical means while possessing a sizeable nonlinearity. The ability to engineer confinement potentials in microcavities makes polaritons a very convenient system to study localized bosonic populations. One bright example is a polariton Josephson junction, where coupling of two polariton populations gives rise to a nontrivial dynamics in the system, and is predicted to lead to the Gaussian squeezing or even to a single photon emission under certain conditions.
In this talk, I will demonstrate the manifestation of the dynamical squeezing in the polariton Josephson junction. This effect was revealed by time-dependent second-order correlation measurements using a streak-camera as an ultrafast single photon detector. Dynamical squeezing was remarkably well explained by quantum simulations, which predict dynamical evolution of the squeezing parameters. These results open the way towards generation of nonclassical light in new type of solid-state systems.
