Title: Nonlinear Intersubband Polaritonic Metasurfaces: from second-harmonic generation with beam shaping to widely-tunable THz sources Abstract: Quantum-engineered intersubband transitions in n-doped multiple-quantum-well heterostructures allow one to produce semiconductor films with very large nonlinear optical response. This nonlinear response can be further enhanced by processing semiconductor heterostructures as metasurfaces in which intersubband transitions are coupled to optical modes of the metasurface …
Events at UCFTitle: Point Defects in Crystals: Trapped Atoms for Quantum Technologies Abstract: Point defects in crystals are the solid-state analog to trapped ions. Thus these “quantum defects”, which can be integrated into solid-state devices, have gained interest as quantum sensors and qubit candidates for scalable quantum networks. In this talk, I will introduce some of the basic quantum defect properties desirable …
Events at UCFTitle: Variational processing of partially coherent light in photonic integrated circuits Abstract: Classical and quantum optical fields are naturally described in terms of modes. Modal decompositions underpin our understanding of the generation, propagation, and measurement of multimode light, as exemplified by the Karhunen–Loève expansion for partially coherent fields, density-matrix eigendecompositions, Schmidt decompositions of bipartite states, and the Bloch–Messiah decomposition of Gaussian …
Events at UCFTitle: Inverse designed, densely integrated classical and quantum photonics Abstract: Recent breakthroughs in photonics design, along with new nanofabrication approaches and heterogeneous integration play crucial roles in building photonics for applications including optical interconnects and quantum technologies. This design breakthrough is named photonic inverse design, and refers to efficiently searching through the space of all possible photonic device geometries, within fabrication …
