摘要：
An optical device is disclosed, including a surface emitting laser element having a surface emitting laser which emits a light in a direction which is perpendicular to a substrate face; a light receiving element which monitors the light of the surface emitting laser; a package provided with a region on which the surface emitting laser element and the light receiving element are provided; and a lid which has a window through which passes the light of the surface emitting laser, the window being formed with a transparent member, and which covers the surface emitting laser element and the light receiving element.
