図３は、上記の本実施形態のレーザカプラ１ａを用いた光学ピックアップ装置の一構成例を示す説明図である。この光学ピックアップ装置において、第１パッケージ部材２および第２パッケージ部材３により形成された偏平な形状のパッケージ部材に収納されたレーザカプラ１ａは、その偏平な面が光ディスク２７に対して平行になるように配置されている。レーザカプラ１ａと光ディスク２７との間のレーザ光Ｌの進路には、レーザ光Ｌを屈曲させる反射ミラー２５が所定の位置に配置される。また、この反射ミラー２５と光ディスク２７との間には、光ディスク２７上にレーザ光Ｌの集光を行う対物レンズ２６が所定の位置に配置される。 3 is an explanatory diagram showing an example of the configuration of an optical pickup device using the laser coupler 1a of this embodiment. In this optical pickup device, the laser coupler 1a is housed in a flat package member formed by a first package member 2 and a second package member 3 , and is positioned so that its flat surface is parallel to an optical disk 27. A reflecting mirror 25 that bends the laser light L is disposed at a predetermined position on the path of the laser light L between the laser coupler 1a and the optical disk 27. In addition, an objective lens 26 that focuses the laser light L on the optical disk 27 is disposed at a predetermined position between the reflecting mirror 25 and the optical disk 27.
