Recent theory predicted a new class of photonic composite materials that its properties are derived by the structure rather than chemical compositions which promise unprecedented electromagnetic properties that do not exist in the nature such as optical magnetism and negative refraction. Especially, superlens made of metamaterials breaks the fundamental diffraction limit, which may have profound impact in wide range of applications such as nano-scale photonics, electronics manufacturing, and biomedical imaging. I'll discuss recent progress that demonstrated the intriguing physics. We created the first bulk optical metamaterials that show the negative refractions. We demonstrated the superlens and optical cloak using carefully design of plasmonic materials dispersions. The recent discoveries on new topological symmetry such as Mobius symmetry in metamaterials reveals fundamentally new realm of physical properties that do not occur in nature materials. I will further discuss an array of new technologies based on superlens for nano-scale lithography that may transform the next generation of nano-manufacturing, along with plasmon lasers, a coherent light at molecular scale.

近年來，理論預測有一種新型的光子合成材料，它的性質衍生自其結構，而不是其化學組成，有望帶來前所未有的電磁性質，這些性質不存在於自然界，例如光磁性和負折射。特別地，由超材料製成的超級透鏡突破了基本的繞射限制，這將在許多科技應用方面造成深遠的衝擊，例如奈米光子學、電子製造、和生醫顯影術。 我將談論近年來非常奇特有趣的物理進展。我們創先製作出塊狀的，具有負折射率的光學超材料。我們仔細利用電漿材料色散的設計，展示了超級透鏡和光學斗篷。最近在拓樸對稱的新發現，例如Mobius 對稱，從基本上揭開了不存在於自然界材料的物理性質的嶄新領域。我將進一步討論一系列的全新科技，奠基於應用在奈米微影蝕刻技術的超級透鏡。這些新科技將全然改觀下一世代的奈米製造和電漿子雷射（一種分子尺度的相干光源）。 （感謝台灣師範大學物理系林明瑞名譽教授協助翻譯）

I will discuss recent development in scaling down photonics. First I will present theoretical and experimental investigation of passive low loss waveguide using hybrid plasmon design. We propose a new optical cavity design approach using indefinite medium that has a drastically different scaling law than conventional microcavities, and discuss its experimental demonstrations. We will show an active plasmonic laser circuit that integrated with 5 tiny cavities that multiplexed into a single waveguide-an effort towards integrated photonics at nano-scale. Finally if time allow, I will discuss photonic spin hall effect that provides a new channel for photonic information transfer. References: Rupert F. Oulton, Volker J.

我將討論在比例微縮光子學方面的新進展。首先我將介紹無源低損耗波導的理論和實驗探討，這種波導是利用混合電漿子設計而成。我們提出一種新的，利用不特定介質的光腔設計。這種設計，對比傳統的微腔，具有極為不一樣的標度律。我將討論它的實驗示例。我們將展示一種有源的電漿子雷射電路，其內以積體方式製作五個很小的空腔，多路傳輸進入單一的波導。這是朝向奈米積體光子學的一種努力。最後若時間允許，我將討論光子自旋霍爾效應，可提供做為光子資訊傳送的新通道。 （感謝台灣師範大學物理系林明瑞名譽教授協助翻譯）
