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 …
CREOL CalendarTitle: 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 …
CREOL CalendarTitle: An operator-based approach to classifying topology in open and nonlinear systems Abstract: In this talk, I will provide an overview of some of the outstanding problems in the classification of topological materials in physical systems, and I will discuss how many of these problems can be addressed through the spectral localizer framework. For example, the chiral edge states that are guaranteed …
CREOL CalendarTitle: 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 …
