C05 - Quantum cooperative helical metafilms for producing nonclassical light

Summary

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.
