可轉貼可高度拉伸超薄隨機雷射標籤在各種基板之光 學研究分析與應用演示

Abstract

隨機雷射比起傳統雷射擁有許多先天的優勢像是裝置可彎曲性、微小體積、低成本、設計簡單以及量產的可能性。隨機雷射已經在近十年成為非常熱門的研究領域。我們的隨機雷射標籤整合了隨意轉貼在各種非傳統基板的製程設計、可彎曲的材質以及溫度感測的功能於單一裝置。超薄隨機雷射標籤不僅僅可以持續穩定地在500 次以上拉伸壓縮100 %的嚴苛條件下繼續正常運作，甚至還可以用簡易的製程方法轉移到任意的基板不管是彎曲、非平面以及粗糙的材料上面。除了上面所述的功能之外，超薄隨機雷射標籤還可以用於人類體溫的感測。超薄隨機雷射標籤這樣的先進的光學裝置有很大的潛力在許多各式各樣的領域上運用。

Random lasers have abundant inherent advantages compared to conventional lasers such as flexibility, size, cost, simple design, and mass production. It has been the hot research topic in recent decades. An integrated random laser label with transferability, flexibility and temperature sensing is created and demonstrated in this work. The ultrathin stick-type random laser (USRL) can not only function stably under 100% strain with at least 500 times test but could also be easily transferred on arbitrary substrates disregard the material is rigid, flexible, non-planar or rough. In addition to features mentioned above, random laser signals could be stimulated and controlled repetitively within human body temperature. This shows great potential that the USRL can serve as photonics modules for further advanced developments of a variety of applications covering many different fields.
