Abstract: A wavelength measuring system includes a lens for converting an outgoing light beam from an input fiber into parallel light rays, a first wavelength dispersion element disposed on the optical axis of the parallel light rays for spectral diffraction of the parallel light rays and a second wavelength dispersion element disposed opposite to the first wavelength dispersion element so as to allow the parallel light rays, after spectral diffraction by the first wavelength dispersion element, to fall thereon. A right-angle reflecting prism divides the parallel light rays from the second wavelength dispersion element into two reflected light beams. First and second optical receivers receive the reflected light beams from the right-angle reflecting prism, respectively, and a signal processing circuit processes signals from the first and second optical receivers, respectively, thereby determining the wavelength of an incoming light beam for measurement. Thus, the wavelength measuring system is compact in size and low in cost. The wavelength measuring system has no movable mechanical parts, and does not require software for data processing when measuring the wavelength of a light wave oscillating in a single mode and in a wide wavelength range at a light source.

Abstract: One end of semiconductor laser 1 is coated an antireflection film 1A. And, the external resonator is constructed with a diffraction grating 2 and an external reflective mirror 4. Additionally, a beam splitter 3 is provided between the diffraction grating 2 and the external reflective mirror 4. An output light from antireflection film 1A of semiconductor laser 1 is transformed to a parallel light by the convex lens 5A, and is supplied to the beam splitter 3. The parallel light 13A changes a light path thereof at beam splitter 3, and is then supplied to the external resonator. A wavelength of the parallel light 13A is determined by the diffraction grating 2, so that the light has a selected wavelength, and a phase which is matched with a phase condition of the external resonator. A portion of the resonated light is reflected by the beam splitter 3, and is fed back to the semiconductor laser 1 via convex lens 5A, as a reflected light. When the light is fed back, the semiconductor laser 1 outputs a light of narrow spectral line width. This light is outputted from another end, which is not coated with antireflection film 1A, of semiconductor laser 1, and is transformed to a parallel light by the convex lens 5B. This parallel light 13B forwards to a light isolator 6, is then collected at optical fiber 8 by the convex lens 7. The light which supplied at optical fiber 8 is output to an external apparatus.

Abstract: A strong magnetic thrust force type actuator includes a first type of actuator, the permanent magnets of which are inserted between plate members of the primary magnetic member. When a coil disposed upon the primary magnetic member is energized magnetic flux flows from a facing portion formed with a secondary magnetic member to one of the plate members, and then, to an adjacent plate member through one of the permanent magnets. Within this adjacent plate member, additional magnetic flux flows therein from another adjacent plate member through another permanent magnet. In a second type of actuator, the permanent magnets of which are inserted between side surfaces of facing portions formed with the secondary magnetic member, a magnetic flux flows from a facing portion formed with the primary magnetic member to a facing portion of the secondary magnetic member, and then, to an adjacent facing portion through of the secondary magnetic member through means of a permanent magnet, and within this adjacent facing portion, additional magnetic flux flows from another adjacent facing portion through means of another permanent magnet. Thus, as long as the pulse current flows within the coils wound around the primary magnetic member, all facing portions of the primary magnetic member contribute to the production of the magnetic thrust.

Abstract: An optical star coupler having a biconically tapered optical star coupler suspensively inserted in a protection tube and the method for manufacturing the same are disclosed, and the manufacturing method is that an optical fiber bundle is inserted into a protection tube such as hollow glass tube, then the optical fiber bundle is twisted and pulled while it is indirectly heated through the protection tube, thereby to form a twisting, fusing and pulling portion, and both ends of the protection tube are sealed with an adhesive agent to fix the optical fiber bundle to the protection tube. This optical star coupler can be constructed so as to be connected in tandem without any splicing.
