在這次的研究中，我們證明了一項新式溫度感測器的作法，是將雙金屬片與直線式陡變熔拉馬赫詹德干涉儀(Abrupt-tapered Mach-Zehnder interferometer，AT-MZI)作結合。雙金屬的彎曲作用力來自於其雙金屬對環境溫度變化俱有高敏感度。
首先，將一段鉺鐿共掺光纖(Erbium Ytterbium co-doped fiber，EYDF)置放在熔拉平台中，利用微型火燄破壞其絕熱條件，使光纖呈現融熔狀態後，快速向外拉伸，即可製作出直線式兩點陡變熔拉馬赫詹德干涉儀。之後將雙金屬片置放在干涉儀的兩點陡變點及傳輸區進行量測，藉由溫度控制器使雙金屬因受溫度變化而產生的作用力，造成量測點的形變，達到波長位移的目的。此架構強化了直線式陡變熔拉馬赫詹德干涉儀對溫度的敏感性與精確度。此外，還研究雙金屬在不同固定方式下對干涉現象會有何改變。
最後，有別於其他溫度感測應用，此感測器優點有著架構簡單、製作成本低廉以及在未來的研究中能高度實現非接觸式的溫度感測。

In this work, we demonstrate micro in-line fiber temperature sensors based on abrupt-tapered Mach-Zehnder interferometer with bimetal. Bimetal is known to be sensitive to ambient temperature variation with its structure automatically being curled. By doing so, the bimetal strip is mounted on abrupt-tapered Mach-Zehnder interferometer to bend the abrupt tapers and phase-shifters to enhance the accuracy and sensitivity of the temperature measurements. The influence of the physical positions for the bimetal is also investigated. This temperature sensor is simple, cost-effective, and is highly promising for many kinds of temperature sensing applications with non-contact requirements in the future.
