The National Science Foundation (NSF) awarded a $409,834 Project Grant under the Engineering program (CFDA 47.041) to the University of Cincinnati to design, fabricate, and characterize electrically pumped topological nanowire photonic crystal surface emitting lasers and defect robust topological insulator lasers. These novel laser technologies are intended to replace metal chip interconnects with micrometer-sized photonic devices, enabling higher bandwidth and lower power consumption for future photonic integrated circuits. The research project, running from September 2024 to August 2027, will involve modeling, simulation, and experimental characterization of the topologically enhanced nanowire photonic crystal lasers. This work aims to advance the development of high-performance, energy-efficient integrated photonic technologies for information technology applications.
