Nanophotonics in Low-Dimensional and Atomic-Layer Materials
Nanophotonics, Metasurfaces, Plasmonics, Two-Dimensional Materials, Quantum Dots, Light–Matter Interaction
Overview
Low-dimensional materials have emerged as promising platforms for nanophotonic and optoelectronic applications owing to their unique optical properties and atomically thin dimensions. A key challenge in developing practical nanophotonic devices based on low-dimensional materials is the realization of on-chip photonic structures that can be seamlessly integrated with these materials while enabling strong light–matter interactions at the atomic scale. To address this challenge, our research focuses on the design and development of nanophotonic, plasmonic, and metasurface platforms, together with original nanofabrication techniques specifically tailored for low-dimensional materials.
Novelty and originality
・Ultrathin, high-Q nanophotonic and metasurface architectures based on freestanding structures and BIC/quasi-BIC resonances, enabling strong optical confinement and enhanced light–matter interactions at the atomic scale.
・Bidirectionally tailored integration of low-dimensional quantum materials and photonic structures, co-optimizing both material properties and optical architectures to overcome mode mismatch and maximize light–matter coupling.
・Large-area, transfer-free precision nanofabrication technologies tailored to colloidal quantum dots and 2D materials, including original fabrication protocols for ultrathin photonic membranes while preserving their optical properties.
・On-chip integrated nanophotonic platforms compatible with established semiconductor fabrication processes, providing a scalable pathway toward practical low-dimensional-material-based photonic and optoelectronic devices.
Details
My research focuses on establishing a new paradigm in nanophotonic architecture, overcoming the fundamental limitations that have long hampered progress in quantum-material-based nanophotonics. I introduced the original concept of the ultrathin, freestanding nanophotonic membrane and demonstrated that such a substrate-free architecture, tailored to the dimensional scale of low-dimensional quantum materials, can significantly enhance their intrinsic optical properties and maximize light–matter interactions. This platform enables the integration of quantum materials into high-performance nanophotonic devices, achieving substantial enhancement of light–matter interactions.
Summary
To fully exploit the exceptional optical properties of low-dimensional quantum materials, my research aims to establish a new nanophotonic framework in which material properties and photonic architectures are co-designed to control light–matter interactions at the atomic scale. In particular, by combining ultrathin freestanding nanophotonic membranes, metasurfaces, high-Q resonant structures, and original nanofabrication techniques, we are developing new platforms for integrating low-dimensional materials and quantum dots into high-performance photonic devices. Ultimately, these technologies are expected to enable advanced on-chip quantum and photonic devices, as well as next-generation optoelectronic systems.
