摘要： In an optical monitor for monitoring signal lights from a plurality of optical fibers, emission surfaces of the plurality of optical fibers are arranged along a straight line, and a photodetecting surface of a photodetecting element disposed so as to face the emission surfaces is moved in parallel to the straight line along which the emission surfaces are arranged in such manner that light from each of the emission surfaces is received by the photodetecting element, so that the plurality of signal lights are made incident on the photodetecting element successively. The present optical monitor thereby is capable of monitoring a large number of transmission paths while requiring a small number of components.

摘要： The present invention is directed to a photoconductive switch module. The photoconductive switch module comprises a first substrate having light-emitting elements, and a second substrate having photoconductive switch elements, whose number is equal to that of the light-emitting elements. The light-emitting elements face the photoconductive switch elements, so that the photoconductive switch elements are turned on/off in accordance with lighting/extinction of the light-emitting elements. The photoconductive switch module further comprises a third substrate arranged between the first substrate and the second substrate. The third substrate has through holes, whose number is equal to that of the light-emitting elements. Each through hole is positioned between a light-emitting element and a photoconductive switch element facing each other. Drive light emitted from each light-emitting element travels to the photoconductive switch element via the through hole.

摘要： A laser beam emitted from a laser source provided at a silicon substrate passes through a hologram element formed of a translucent flat plate and a grating, thereby being subjected to NA conversion executed by an NA converting lens, passing through a polarizing film of a polarization beam splitter, and converging onto a magneto-optical disk via a collimator lens and an objective. A part of back-reflection from the magneto-optical disk, which is reflected by a polarizing film of the polarization beam splitter, is reflected by a reflection surface of the splitter, then branched into two polarized light beams by a Wollaston prism, and guided to one light receiving element group. On the other hand, another part of the back-reflection, which passes through the polarization beam splitter, is branched into two beams by the hologram element and guided to the other light receiving element groups.
