Title: 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 …
CREOL CalendarTitle: Frequency-Comb-Based Optical Timing Networks Abstract: The optical frequency comb has enabled a wide range of frequency, time and distance metrology applications due to its precise, rigid, and referenced optical output. However, the very rigidity which makes the frequency comb an excellent time-frequency ruler places limits on its applicability for comb-based sensing applications with many operating far from quantum-limited sensitivity. For instance, …
