摘要： An optical attenuator includes an attenuating section arranged between a receiving waveguide coaxial with a receiving optical fiber and a transmitting waveguide coaxial with a transmitting optical fiber to attenuate the intensity of light emitted from the receiving waveguide. In the optical attenuator, an actuator drives a movable section across the propagation of light. An inner housing has a cover mounted with the receiving and transmitting waveguides in an underside and a body arranged and bonded under the cover. The receiving and transmitting waveguides can be arranged in a cavity of the body without interference. An outer housing contains the inner housing to protect the same. A calibrating section generates attractive force from above the cover to pull the movable section against the latitudinal deformation thereof so that optical axes of the attenuating section and the receiving and transmitting sections are coaxially aligned, compensating the vertical deformation of the movable section, in order to minimize the initial insertion loss of light as well as improve optical properties of a final product.

摘要： 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.

摘要： The present invention relates to a microlens fabrication method for fabricating a non-global microlens from a multi-layer substrate. In the microlens fabrication method of the invention, a first layer of a predetermined etching rate is formed first, and then a second layer is formed on the first layer. The second layer has a predetermined etching rate different from that of the first layer. A mask pattern in use for etching is formed on the second layer, and then the first and second layers are etched to form a non-spherical lens contour therein.
