Description
いくつかの実施形態では、2つの分離したV溝が形成されてもよい。好ましくは、V溝は、同じマスクを使用して形成され、同時にエッチングされる。第1のV溝の一部分は、端部分138を位置付け、方向付けるために使用されてもよく、第2のV溝の一部分は、もう1つの端部分140を位置付け、方向付けるために使用されてもよい。V溝204は、光ファイバーシステム200のそれらのそれぞれの端部分138、140を周知の方法で位置付け、方向付けるので、光学素子は、光ファイバーシステム200の端部214、216によって放出されるおよび/または受け取られる光を処理するために、任意の望ましい構成で配置することができる。
