About us

Silicon photonic platform, by leveraging the well-established CMOS fabrication, allows researchers to explore the full potential of nanophotonics while staying connected to practical applications. In our group, NCTU SNG, we study nanostructures, especially those compatible to mass-producible CMOS technology. This means the nanostructures we study is not only fundamentally cool and exciting to us, but can make an impact to the society. We like to use nanostructures to manipulate light in all aspects: guiding, bending, scattering, diffracting, enhancing, focusing, imaging and etc. We believe, in nanophotonics, “there’s plenty of room at the bottom,” as physicist Richard Feynman said about nanotechnology in 1959. In particular, we like to use the concept of metamaterials. This means we design nanostructures that are small compared to the wavelength of light. So light doesn’t see the details but sees the nanostructure as a homogenized, artificial material. It is like we can create new optical materials that don’t exist in nature! We also like to incorporate emerging new materials  into silicon photonic platform. In particular, we are interested in 2D materials. The family of these atomic-thin materials, including graphene, TMDs (transition metal dichalcogenides), h-BN and etc., can bring many new functionalities. The applications of our research include but not limited to: LIDAR (Light Detection and Ranging), sensors, communications, biomedical optics, imaging and display. We summarize our research interests with the following figure:

在交通大學矽奈米光子實驗室,我們的興趣在於理解光在奈米結構中的物理現象,並應用奈米結構去操控光的行為,如光的侷限、彎曲、散射、繞射、增強、聚焦、成像等等。我們特別著重於可相容於CMOS製程的奈米結構。這是因為在矽光子的領域中,奈米結構的使用不再只是學術上有趣的題目,更是可量產的可靠方法。我們追隨物理學家理查.費曼在1959年對奈米科技的評論:“there’s plenty of room at the bottom.” 其中我們運用超穎材料的概念,藉由設計小於光波波長的奈米結構,產生自然界現存材料不易達到的材料特性。我們也感興趣於將新材料引入矽光子領域,特別是二維材料可藉由凡德瓦力轉移到任意基材,可提供各具備各種功能性的高品質二維晶體。本實驗室的應用方向包含包括無動件光學雷達、微型感測器、光通訊、生醫檢測、成像與顯示技術等。
