串聯微米球之光子奈米噴流傳播模態的數值分析與實驗

微米圓球呈線性排列時，所引起的光子奈米噴流傳遞現象，稱之為奈米噴流傳播模態。本論文使用時域有限差分法建立串聯微米圓球的數值分析模型，微米圓球直徑分別為1.9μm、5μm、10.1μm，折射率為1.59，在模擬結果中，觀察光子奈米噴流傳播模態與傳播的行為，並計算其衰減率、散射以及傳播損失。本論文建立了一套量測光子奈米噴流的量測系統，試片準備我們使用直徑為3μm、5μm、8μm以及126μm的聚苯乙烯微米圓球，並且利用半導體製程製作可讓微米圓球自主性排列組合的基板，利用物鏡將雷射光束聚焦導入光纖內，再經由光纖導入呈線性串聯的聚苯乙烯微米圓球上，最後利用光纖將光的傳遞效果導入光譜儀中，進而取得光譜數據，並與其模擬結果互相驗證，此研究結果將有助於解決高科技產業中奈米等級的影像量測與傳輸問題。

In this paper, we observed the optical transport phenomena of linear arrays of polystyrene spheres that can be called the nanojet-induced modes. We established a numerical mode of linear arrays of polystyrene spheres by using the FDTD with refractive index 1.59 and diameters 1.9μm, 5μm and 10.1μm. In simulation, we have calculated the transmission, reflection and propagation loss of the nanojet-induced modes. We developed an efficient measurements system for nanojet-induced modes. The 3μm, 5μm, 8μm and 126μm polystyrene spheres are deposited on a patterned substrate by using a self-assembly of polystyrene spheres. The laser beam is focused into the optical fiber by using an objective lens. Another optical fiber is used to collect the light propagation and connect with a spectrometer. The experimental results are compared with the simulation results. The results in this study can be used to solve the image measurements and transmission problems in the high-tech industries.
