| 技術摘要 / Our Technology： |
本發明係有關一種可調式長週期光纖光柵結構及製造方法，係藉由溫度之調整，材料間熱膨脹係數的不匹配使光纖產生預期之微彎曲變形，形成一類似傳統光柵發生模態耦合的現象，進而達到以溫控來調變濾波頻譜的功效，除可應用在光通訊暨分波多工元件設備上，亦可應用於溫度及變形的偵測。本發明之一種可調式長週期光纖光柵結構，係包括：一基材，其上具週期狀結構，具有一第一熱膨脹係數；一接合劑，係固定一光纖於該週期狀結構，具有一第二熱膨脹係數；其中，該第一熱膨脹係數與該第二熱膨脹係數係不相同，在溫度變化下，兩材料，即基材與接合劑之熱膨脹係數不一致造成光纖呈現微彎曲之現象，形成一類似光柵的效果。
The invention discloses a tunable long period fiber grating structure and fabrication method, which produces an expected microbending deformation by adjusting the temperature and making use of the unmatched coefficients of thermal expansion between different materials, and thus creating a phenomenon of mode coupling effect occurred in traditional optical gratings in order to provide the structure and fabrication method for having an effect of tuning spectra by controlling the temperature. This invention not only can be applied to the optical communications and wavelength dependent multiplexed devices and equipments, but also can be applied to the temperature and deformation detection. The tunable long period fiber grating structure in accordance to the present invention comprises a substrate; a periodic structure being disposed thereon and having a first coefficient of thermal expansion; a coupling agent, having a second coefficient of thermal expansion for fixing a fiber to the periodic structure; wherein the first and second coefficients of thermal expansion are different.
