摘要： There is disclosed an optical switch consisting of a support substrate, a movable raw optical fiber, a fixed raw optical fiber, a magnetic member for the movable raw optical fiber, and a leaf spring. The fibers are disposed in a V-shaped groove formed in the substrate. The magnetic member is actuated by an electromagnet disposed above the substrate. The leaf spring pushes the movable raw optical fiber into the V-shaped groove. The structure of the switch is relatively simple. Since the movable raw optical fiber is pushed using the leaf spring, the switch is less affected by the assembly accuracy than conventional. It is easy to make adjustments during assembly. Consequently, high-performance, low-cost, optical switch that can be mass-produced can be offered.

摘要： It is an optical information recording and reading apparatus for recording and/or reading information at a high density by using a near-field light-generating device as a near-field optical head. The end surface of the core of a flexible optical waveguide is formed in an intermediate position in the optical waveguide and in a portion fixed to the near-field optical head. Light for recording and reading information is spread within the clad. The spread light flux is reflected toward the near-field optical head by a reflective surface formed on the side of one end of the optical waveguide. The reflected light flux is collected by light-collecting structures and then is made to enter an optical minute aperture formed in the near-field optical head. Near-field light is created near the minute aperture. Light scattered by the surface of the recording medium is received. Thus, information on the recording medium can be recorded and read.

摘要： There is disclosed a near-field optical head having an microscopic aperture whose size can be varied. The optical head comprises a substrate of silicon. A hole in the form of an inverted cone is formed in the substrate. The top portion of this hole forms the microscopic aperture. A support portion for supporting an actuator is formed on the substrate. The actuator holds a light-blocking film in such a way that the light-blocking film stays in the hole and that the bottom surface of the light-blocking film is flush with the bottom surface of the microscopic aperture. The light-blocking film is moved by the actuator to change the aperture to desired size.
