Abstract:
1. An optical wavelength switch comprising: a first and a second slab wave guides; an array wave guide connected with the first and the second slab wave guides; a movable mirror array having a plurality of reflecting mirrors, arranged on the second slab wave guide opposite to the side where the array wave guide is connected therewith; and an optical wave guide arranged on the first slab wave guide opposite to the side where the array wave guide is connected therewith, for inputting an input optical signal wavelength-multiplexed and outputting an optical signal wavelength-demultiplexed from the input optical signal, wherein the optical wavelength switch has a focal point of an output optical beam from the second slab wave guide at the positions of the plurality of reflecting mirrors constituting the movable mirror array, the optical wavelength switch operable to switch the route of the optical signal reflectively inputted to the second slab wave guide, depending on the set direction of reflection of the plurality of reflecting mirrors; wherein the plurality of reflecting mirrors constituting the movable mirror array have dented reflecting faces, and wherein the angle of reflection of the reflecting mirrors is set by moving the dented reflecting faces along a direction perpendicular to the optical axis.
