Quantum cooperative helical metafilms for producing nonclassical light (C05)

• Subject Area: Experimental Condensed Matter Physics ; Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 429529648

We study the quantum cooperative effects in the linear and nonlinear optical response of helical metafilms. By engineering the metafilms, we aim to achieve high values of the second-order nonlinear susceptibility. This susceptibility will be used to generate pairs of entangled photons through spontaneous parametric down-conversion. By spatially modulating the metafilm properties, we will tailor the entanglement of photon pairs, including orbital angular momentum (OAM) entanglement.
