Abstract: Disclosed herein is a cantilever-type PLC optical attenuator. The optical attenuator includes a base substrate made of silicon, an input waveguide, and output waveguide. Front portions of the upper and lower silicon substrates around the output waveguide are thinner than rear portions of the upper and lower silicon substrates around the output waveguide to provide a cantilever part having upper and lower cantilever substrate parts. A first electrode is provided on a bottom of the lower cantilever substrate part, and a second electrode is provided on the base substrate to electromagnetically correspond to the first electrode. When a voltage is applied between the first and second electrodes, the cantilever part moves up and down by an electromagnetic force, thus controlling the output light.

Abstract: Disclosed herein is a spectacles and sunshade clip assembly using magnets. The magnets serve to detachably attach the sunshade clip to the spectacles. The spectacles comprises a pair of lens frames connected to each other by means of a nose bridge, and temple arms connected, respectively, to the lens frames by means of magnetically-induced hinges. The sunshade clip comprises a pair of sunshade lenses formed by cutting a colored plastic plate into a desired lens form, and a sunshade bridge formed by injection molding and adapted to connect the sunshade lenses to each other. Two magnet ribs are coupled to opposite outer ends of the sunshade lenses to extend in opposite directions. Each of the magnet ribs is configured to substantially coincide with the outer contour of the hinge provided at the spectacles and has a magnet mounted to face the hinge.
