Overview
Low-dimensional materials have emerged as promising candidates for applications in nanophotonics and optoelectronics due to their unique optical properties and atomic scale. A major issue in developing practical low-dimensional materials-based nanophotonic devices is realizing photonic structures via on-chip fabrication with low-dimensional materials, enabling strong light-matter interaction within atomic scale. In my research, I design and develop nanophotonic, plasmonic, and metasurface platforms, as well as original nanofabrication techniques, specifically tailored for low-dimensional materials.
Novelty and originality
・High-quality low-dimensional material-based nanophotonic structures for on-chip integrated devices
・Large-area and non-transfer top-down nanofabrication technologies tailored to colloidal quantum dots and 2D materials
・Compatibility with well-established semiconductor fabrication processes
・Nanophotonics and metasurface design enabling efficient coupling of light into the atomic scale, ensuring strong light-matter interaction and high quality factor
Details
Here, the works based on perovskite QDs, including on-chip integrated single-mode lasers, nanolaser-waveguide coupled photonic circuits, metasurface-based surface-emitting lasers, and plasmonic hot-electron photodetection devices, have been developed and presented by utilizing superior quantum efficiency and recrystallization properties of perovskite QDs.
Summary
My research positioning is to bring the potentials of low-dimensional materials into real integrated nanophotonics by coupling these advanced photonic materials, new-design nanophotonic platforms, and original on-chip nanofabrication, and further to push the limits of nanophotonics via low-dimensional materials.
