Abstract
本發明提供一種光纖裝置,其包括一光纖及一鏡片。該光纖一端開設有一容置槽。該鏡片容置於該容置槽內,並包括一基片及一形成於該基片上的光纖光柵。該光纖光柵包括多個堆疊於該基片上且折射率週期性變化的膜層。如此,該光纖光柵可以通過生產效率較高的鍍膜工藝形成,例如蒸鍍或者濺鍍。另外,採用鍍膜工藝,可選擇的材料較多,材料的折射率變化範圍廣,可以製作各種目的的光纖光柵,從而改善製作空間。
Description
本發明涉及光纖技術,特別涉及一種具有光纖光柵的光纖裝置。
光纖光柵是利用纖芯材料的光敏性,通過紫外光曝光的方法將入射光相干場圖樣寫入纖芯,在纖芯內產生沿纖芯軸向的折射率週期性變化,從而形成永久性空間的相位光柵,其作用實質上是在纖芯內形成一個窄帶的(透射或反射)濾波器或反射鏡。當一束寬光譜光經過光纖光柵時,滿足光纖光柵布拉格條件的波長將產生反射,其餘的波長透過光纖光柵繼續傳輸。然而,如果不進行特殊處理而直接用紫外光照射,纖芯的折射率增加僅為10-4的數量級便已經飽和,因此,為了滿足高速通信的需要,提高光纖光敏性日益重要,目前光纖增敏方法主要有以下幾種:(1)摻入光敏性雜質,如:鍺、錫、硼等;(2)多種摻雜(主要是硼/鍺共接;(3)高壓低溫氫氣擴散處理;及(4)劇火。然而,這樣的製作方法一來麻煩,效率低,二來,對纖芯光敏性的提高也有極限,無法製作符合各種目的的光纖光柵,製作空間受限。
有鑒於此,有必要提供一種可提高效率且改善製作空間的具有光纖光柵的光纖裝置。
一種光纖裝置,其包括一光纖及一鏡片。該光纖一端開設有一容置槽。該鏡片容置於該容置槽內,並包括一基片及一形成於該基片上的光纖光柵。該光纖光柵包括多個堆疊於該基片上且折射率週期性變化的膜層。
如此,該光纖光柵可以通過生產效率較高的鍍膜工藝,例如蒸鍍或者濺鍍,形成。如此,可提高效率。另外,採用鍍膜工藝,可選擇的材料較多,材料的折射率變化範圍廣,可以製作各種目的的光纖光柵,從而改善製作空間。
請參閱圖1至圖3,本發明較佳實施方式的光纖裝置100包括一光纖10及一鏡片20。該光纖10一端開設有一容置槽12。該鏡片20容置於該容置槽12內,並包括一基片22及一形成於該基片22上的光纖光柵24。該光纖光柵24包括多個堆疊於該基片22上且折射率週期性變化的膜層242。
如此,該光纖光柵24可以通過生產效率較高的鍍膜工藝,例如蒸鍍或者濺鍍,形成。如此,可提高效率。另外,採用鍍膜工藝,可選擇的材料較多,材料的折射率變化範圍廣,可以製作各種目的的光纖光柵,從而改善製作空間。
該光纖10包括一纖芯14及一用於保護該纖芯14的包履層16。該容置槽12開設在該包履層16上,呈圓片狀。
該鏡片20與該容置槽12形狀匹配,並通過結構配合卡設於該容置槽12。當然,該鏡片20也可以通過其他手段,例如黏膠,容置於該容置槽12內,此時,並不要求該鏡片20與該容置槽12形狀匹配。
該基片22為圓片狀的玻璃片,可以具有屈光能力(即具有曲面),從而該鏡片20與該光纖10共同構成一透鏡光纖(lensed fiber)。當然,該基片22也可以也可平板狀。
該光纖光柵24為均勻光纖光柵、均勻長週期光纖光柵、切趾光纖光柵、取樣光纖光柵或線性調頻脈衝(chirped)光纖光柵,並利用合適的材料通過物理氣相沉積的鍍膜方式形成。
綜上所述,本發明確已符合發明專利之要件,遂依法提出專利申請。惟,以上所述者僅為本發明之較佳實施方式,自不能以此限制本案之申請專利範圍。舉凡熟悉本案技藝之人士援依本發明之精神所作之等效修飾或變化,皆應涵蓋於以下申請專利範圍內。
