Description

そこで、本実施例では、他の接続方法として、二つのフェルール３、３間にマイクロレンズアレイ１５を挿入する。この実施例２のマルチコアファイバ用接続器について、図５を用いて説明する。図５に、実施例２の概念図を示す。２００はマルチコアファイバのコア部、３００はマルチコアファイバのクラッド部である。なお、左右の一対のフェルール３は、別な部材（図示略）により、相対的な位置関係が固定される。マイクロレンズアレイにより一対のフェルール３、３を接続することで、フィジカルコンタクトの場合と比較して、同等な接続損失を得るために要求される研磨精度が緩和される。マイクロレンズアレイ１５の例として、ナノインプリント技術を用いた屈折率整合レンズ型マイクロレンズアレイがある。 Therefore, in this embodiment, as another connection method, the microlens array 15 is inserted between the two ferrules 3 and 3. The multi-core fiber connector of Example 2 will be described with reference to FIG. FIG. 5 shows a conceptual diagram of the second embodiment. Reference numeral 200 denotes a core part of the multicore fiber, and 300 denotes a clad part of the multicore fiber. The pair of left and right ferrules 3 are fixed in relative positional relationship by another member (not shown). By connecting the pair of ferrules 3 and 3 with a microlens array, the polishing accuracy required to obtain an equivalent connection loss is reduced as compared with the case of physical contact. An example of the microlens array 15 is a refractive index matching lens type microlens array using a nanoimprint technique.

そこで、図６に示す通り、マルチコアファイバの束線１８、マルチコアファイバ接続器１とマルチコアファイバ接続器用光ファイバアダプタ１７、２０を用いることで、パッチパネル１６やインターフェースパネル１９の面積の増大の問題を解決することができる。

Therefore, as shown in FIG. 6, the use of the multicore fiber bundle 18, the multicore fiber connector 1, and the multicore fiber connector optical fiber adapters 17, 20 eliminates the problem of an increase in the area of the patch panel 16 and the interface panel 19. Can be solved.
