Abstract:
1. An optical device comprising: a first optical component that includes a ferrule that has an optical fiber core therein and an end face oblique with respect to a plane perpendicular to an optical axis; a second optical component that is optically coupled to the first optical component; a lens that is placed between the first optical component and the sea rid optical component, and is positioned so that a trajectory of a focal point formed when the first optical component and the second optical component rotate relative to each other falls within a valid region on a surface of the second optical component and the optical coupling does not change; and a housing member that accommodates the first optical component and that includes a stopper that has a through hole through which the optical axis extends, an oblique face that is located outside of the optical axis and is in at least line contact with the oblique end face of the ferrule so that the ferrule and the stopper rotate relative to each other and maintain the at least line contact, wherein said first and second optical components rotate relative to each other by one of: rotation of the first optical component about a center axis thereof, rotation of the second optical component about a center axis thereof, and a combination of rotation of the first optical component about the center axis thereof and rotation of the second optical component about the center axis thereof.
