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: 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 …
CREOL CalendarTitle: Building network of superconducting quantum processors with optical interconnects Abstract: Optically interconnected networks of heterogeneous quantum platforms are milestones of future quantum information infrastructure. Integrating superconducting qubits as the prominent quantum processors in such a network requires efficient and high-fidelity microwave-optical interfaces. In this talk, I will highlight our recent progress towards an electro-optomechanical transducer, which converts quantum-level microwave …
CREOL CalendarTitle: A New Measure: The revolutionary, quantum reform of the modern metric system Abstract: The International System of Units (the SI), the modern metric system, recently underwent its most revolutionary change since its origins during the French Revolution. The nature of this revolution is that all of the base units of the SI are now defined by fixing values of natural constants. …
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: A study in contrasts: epitaxial integration of III-Vs with dielectrics for novel lasers Abstract: This talk will highlight our recent progress in molecular beam epitaxy (MBE) regrowth of laser structures that harness the contrasting properties of III–V semiconductors and dielectric materials to realize new device architectures. In the first part of the talk, I will describe efforts to integrate …
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 …
