摘要： In a nest MZI modulator in which each arm includes a child MZI, the power consumption is reduced. The hybrid integrated-type nest MZI modulator of the embodiment 1a is configured so that, instead of placing a relative phase adjusting section in a parent MZI, a bias electrode Bias 90° in which an electric field is applied in the same direction to the polarization direction in both of the upper and lower arms is placed in each child MZI (see FIG. 4B). The bias electrode Bias 90° provided in each child MZI constitute the entirety of a relative phase adjusting section. The optical signals are subjected to a phase change after the output from the child MZI (see FIG. 1A), because such relative phase adjusting section can subject the optical signals of the upper and lower arms of the child MZI to a shift change in the same direction, respectively.

摘要： An optical modulator having a high stability is provided. In the optical modulator according to the present invention, a phase modulation by an electro-optic effect is made on an optical substrate of an electro-optic material while the setting of an operating point by a thermal-optic effect is made on a planar lightwave circuit (PLC) substrate of quartz, silicon, or the like. Such configuration can suppress the influence of thermal drift or the like because no heat is applied directly to the optical substrate of the electro-optic material. In addition, breakage and warpage of the substrate due to heat are also mitigated. Further, quartz used for the PLC has a low thermal conductivity, approximately one-fifth of that of the LN substrate (approximately 1 W/(m·K)), and therefore, a desired phase difference can be maintained with a low power consumption, and thus, the operating point becomes stabilized.

摘要： A chemical analysis element supplier has a cartridge container for storing a cartridge in which a plurality of chemical analysis elements are stored. The cartridge is inserted into the container through a cartridge insertion port which is formed in the top of the container. An element take-out mechanism takes out the chemical analysis element in the cartridge through an element take-out port which is formed in the bottom of the container. The element take-out mechanism is provided with a lifting member which is operative to move upward through the element take-out port to lift the cartridge in the container so that at least a part of the cartridge projects upward through the cartridge insertion port.

摘要： A chemical analysis film cartridge with a box-like casing body having first and second end walls opposed to each other between which a plurality of dry frameless chemical analysis film chips are stored in a stack. A first opening is formed in a side wall of the casing body near the first end wall so that only the film chip nearest the first end wall can be taken out of the casing body through the first opening by moving the film chip in a direction perpendicular to the stack. A second openings which permits a suction pad to hold the film chip nearest the first end wall and to remove it from the casing body through the first openings is formed in the first end wall. The width of the first opening is larger than the thickness of one film chip and smaller than double the thickness of one film chip over at least a portion of the first opening. The suction pad is retracted with the film chip so that the film chip abuts against the edge of the second opening on opposite sides of the suction pads and then the suction pad is further retracted to pull the central portion of the film chip in this state into the second opening, thereby reshaping the film chip into a predetermined warped-shape conforming to the shape of the first opening.

摘要： The present invention is intended to provide a compact and simple optical semiconductor device that reduces crosstalk (leakage current) between light receiving elements. According to the present invention, since a back surface electrode is a mirror-like thin film, crosstalk to an adjacent light receiving element can be suppressed, thereby reducing a detection error of a light intensity. By disposing a patterned back surface electrode or by disposing an ohmic electrode at the bottom of an insulating film over the whole back surface, contact resistance on the back surface can be reduced. By using the optical semiconductor elements with a two-dimensional arrangement and by using a mirror-like thin film as the back surface electrode, crosstalk can be reduced. By accommodating the optical semiconductor elements in the housing in a highly hermetic condition, the optical semiconductor elements can be protected from an external environment.
