    Abstract: A lens member ( 55 ) is made to adhere to a lead frame ( 36 ) via a transparent adhesive resin ( 41 ) and is not transfer molded with a sealing body ( 37 ). With this arrangement, the transparent adhesive resin ( 41 ) can be used as a member for buffering a thermal stress due to a linear expansion coefficient difference between the lead frame ( 36 ) and the lens member ( 55 ). By using a resin of a low Young's modulus such as a silicon based resin, the damage and deformation of the lens member ( 55 ) can be prevented by largely reducing the thermal stress exerted on the lens member ( 55 ). Furthermore, the linear expansion coefficient can be reduced by adding filler to the sealing body ( 37 ), and the optical coupler can be used under an environment of a wide temperature range of, for example, -40° C. to 115° C.

    Abstract: The deformable mirror (10) includes a first carrier plate (4) with a first reference surface (4a) which can provide a first degree of spherical aberration to incident light. The mirror has a second transparent carrier plate (6) with a second reference surface. The second reference surface lies opposite the first reference surface and causes a second degree of spherical aberration, different from the first, to incident light. A flexible element (1) is arranged between the first and second carrier plates (4,6). The flexible element has a reflective surface and is formed such that it can be matched to the first or second reference surface. A driver (9) is provided to adapt the flexible element to the first or second reference surface. The flexible element (1) is held between the first and second carrier plate. Light radiation reflected by the reflective surface undergoes spherical aberration such that the flexible element is adapted to the reference surface by the driver (9).

    Abstract: PROBLEM TO BE SOLVED: To secure the safety of eyes by preventing laser light from being leaked to the outside of a communication module because there is the danger that when transmission light is irradiated from an LD(laser diode) in a state in which an optical fiber or a connector is slipped off when the LD is used, eyes and the skin of a human beings are injured by the coherent property of the radiant light. SOLUTION: This optical communication module is provided with a radiant member 2 emitting transmission light 1a and a connecting tool for connecting an optical fiber 7 for external transmission attachably and detachably to the radiant member 2 and the connecting tool has a cylinder-shaped containing part which receives the end part of the optical fiber 7 coaxially at the time of connecting the optical fiber 7 and fixes it and, in this module, the radiant member and the connection tool are arranged so that the optical axis of the transmission light from the optical radiant member 2 intersects the optical axis 8 of the optical fiber 7 with a prescribed angle to be made incident on the inside of the optical fiber 7 at the time of connecting the optical fiber 7 and the emitted beam collides with the inner wall of the containing part at the time of attaching and the detaching of the optical fiber 7.

SOLUTION: This device performs transmission/reception with a single optical fiber. A light emitting element 6 emitting a transmission beam and a lens 5 converging the beam and making it incident on the optical fiber 2 are arranged in a transmission space 16. A light receiving element 7 receiving a reception beam from the optical fiber 2 is arranged in a reception space 17. A light separation member 8 separates the transmission space 16 and the reception space 16 optically. Further, the light separation member 8 is provided with an opening part passing the transmission beam S from the light emitting element 6 through and passing the transmission beam S1 reflected by the optical fiber 2 through.
