本實驗目的為觀察在聚苯乙烯微米小球單顆內或直串型球串之光耦合傳遞的情形。光線在膠體小球內的傳遞形態與球的粒徑大小和折射率有關,本實驗利用將小球直接加熱的方法,發現小球在受熱過程中,其粒徑大小和折射率都可有適度的改變,經由一系列的觀察,可對光束傳遞情形做較精準的描述。
將小球受熱約在350℃時,經由量測散射光的相對強度發現有逐漸下降的趨勢,我們認為這主要是樣品受熱使球內折射率逐漸增大,光線經由nanojet-induced modes(NIMs)的效應,其中心最大強度逐漸由球外向球心靠近,所造成的結果。
在長串小球中,我們發現小球在受熱時,接觸點會相互融合,此會降低NIMs的光聚焦效應,而轉變為光波導傳遞模式,所以在光線出口會有較大的散射情形。
本實驗觀察所得結果,可和文獻上理論模擬成果相互驗證。

Our experimental purpose is to observe the light propagation of single polystyrene(PS)micro-spheroid and chained PS micro-spheroids. Based on the theories, the focusing modes of such light propagation are related to the diameter and refraction index of the micro-spheroid. Thus, a method was developed in this experiment to appropriately modulate the diameter and refraction index of the PS micro-spheroid by a heating treatment. With a sequence of observations in different temperature, the light propagation of the micro-spheroid could be accurately described.
We found that the relative intensity( )of the light propagating in the PS micro-spheroid declined with the increase in the ambient temperature, and the declination had a maximum at 350 . According to the nanojet-induced modes(NIMs), we considerably inferred to the heating treatment caused an increase in the refraction index of the PS micro-spheroid and altered the focusing modes of the propagation light. This resulting could be proved by the position of the focusing point, which slightly shifted to the core of the PS micro-spheroid.
In the experiment of observing the light propagation in chained PS micro-spheroids, we found that the contact points between the micro-spheroids were melting during the heating process. This resulting would induce a declination of the light focusing in the PS micro-spheroids. With more time used in heating the micro-spheroids, the light propagation gradually became a simple waveguide which scattered light with lager solid angles in the exit.
Our experimental results could be explained by NIMs theory.
