<p><P>PROBLEM TO BE SOLVED: To provide an interferometer, an optical switch and an optoelectronic integrated device, which facilitate control of light, have superior response characteristics and are miniaturized. <P>SOLUTION: Two optical fibers, second and third optical fibers Of2 and Of3 for branching optical paths, have a tilt edge on one side and a reflecting surface on the other side, and one of them is disposed with respect to a first optical fiber for input so that reflection takes place at the mutual tilt faces and an optical coupling takes place by mutual side lens effect, and the other of the second and the third optical fibers is disposed with respect to the first optical fiber so that the mutual tilt edges are facing to each other with a predetermined gap, a metal mirror is disposed at the edge of the second optical fiber at which the tilt edge is not formed, and a shape memory alloy on the edge of which a metal mirror is formed and which is expanded and contracted according to a temperature change is disposed on the edge of the third optical fiber Of3 at which the tilt face is not formed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
