軟性雙曲超穎材料：奈米光子元件的可撓性、可拉伸性與適應性

Abstract

本論文研究內容結合軟性光子元件與雙曲超穎材料，軟性的光子元件具有可彎曲、可拉伸與可以適應任何基板的特性，並且藉由此特性去增加與創造人與機器互動的機會。雙曲超穎物質是一個在動量空間中擁有雙曲色散曲線的物質，因此雙曲超穎物質具有很高的光子能態密度，而我們可以利用這特性去增強光與物質的交互作用。藉由改變基板與雙曲超穎材料的材料，我們可以創造出一個可拉伸和可以適應在不同底座上的雙曲超穎材料。在實驗中，我們藉由雙曲超穎物質增強光與物質的交互作用的特性，在上面放了半導體量子粒子，創造出一個可拉伸式的隨機雷射，並且在不同基板上的量測，來檢測軟性雙曲超穎材料的可行性。這個結果對於奈米光子元件、穿戴式光子裝置、軟性機器人、植入式醫療裝置會有新的發展。

In this thesis, we combine soft nanophotonic devices and hyperbolic metamaterial (HMM). Soft nanophotonic devices create and enhance the human-machine interactions by deliver their promises of stretchability, flexibility and conformability. An important component of nanophotonic devices, hyperbolic metamaterial has hyperbolic dispersion in its momentum space which provides HMM a large amount of photon density of state to enhance light-matter interaction. By substituting the material of substrate and HMM, we can create soft hyperbolic metamaterial (SHMM) with flexibility, conformability, and stretchability. In this study, we show that the SHMM is able to be used to integrate with semiconductor quantum dots for accomplishing enhanced laser action to check the feasibility of SHMM. This result points out the new development of nanophotonic devices and soft robots, biomedical implants and wearable photonics.
