全海洋隨機雷射之進階光學分析

Abstract

隨著永續科技的發展，具備可生物分解且可與環境相容的光電設備一直是備受渴望但極具挑戰性的議題。在本篇的研究中，我們展示了全由海洋物質組成的全生物材料隨機雷射元件。其中，葉綠素與藍珊瑚骨骼分別作為我們雷射系統的光增益物質和散射媒介。我們所使用的葉綠素萃取自海洋矽藻，而海洋矽藻在海洋中廣闊充足的分佈也使得我們的元件有豐富的資源可以取得。此外，珊瑚骨骼天生具備的奈米柱結構也能很有效的局限住光使其增益以致雷射現象。這個雷射元件的設計拓展出了海洋材料的新穎應用，也使得生物相關光學元件的發展獲得前所未有的幫助。

Towards the sustainable development, optoelectronic devices with biodegradability and biocompatibility have been a desirable but challenging issue for years. In this study, an all-biomaterial random laser device based on all-marine elements has been demonstrated. Chlorophyll and blue coral skeletons serve as gain medium and scattering centers, respectively. The chlorophyll is derived from marine diatoms, which are ubiquitous in the ocean and set up an abundant source for the device. On the other hand, the coral skeletons with intrinsic nanorod structures can provide a strong optical confinement and feedback for laser action. The proposed design signifies the novel application of marine materials and represents a significant step for the development of bio-inspired photonics modules.
