This National Science Foundation (NSF) Project Grant award under the Engineering program (CFDA 47.041) will provide $402,134 from September 1, 2024 to August 31, 2027 to support research and development of a novel class of semiconductor nanostructures called non-Hermitian topological photonic crystals. The key products and services to be delivered include:

  • Designing, fabricating, and characterizing the optical properties and optoelectronic device applications of these photonic crystal slabs, which can support customized non-Hermitian topological modes. This will involve probing the spatial field-intensity distribution and spectral dispersion using photocurrent measurements.

  • Demonstrating novel physical phenomena like the reciprocal-space Su-Schrieffer-Heeger model, the non-Hermitian skin effect, and the breakdown of conventional Bloch band theory through these topological photonic structures.

  • Leveraging the topological effects to develop highly miniaturized photodetectors with advanced light sensing capabilities, including triangulation and ranging, multi-spectral imaging, and wavefront sensing.

The project aims to validate recent theoretical predictions on non-Hermitian topological wave systems and create new design opportunities for compact, high-performance optical sensors with significant implications for computer vision, biomedical imaging, and autonomous navigation applications.
