摘要： A simultaneous bi-directional OTDR optical fiber measurement method wherein a test fiber is spliced between a launch fiber and a termination fiber which is provided with a reflective coating at its terminal end. A laser light pulse is introduced into the launch fiber and the forward trace signal and reverse trace signal from the light pulse are detected. A correction is applied to the reverse trace signal to account for reflectivity originating at the fiber input end so that an accurate measurement can be made of certain fiber characteristics of a single-mode optical fiber.

摘要： A solution containing a target compound is passed through a trap column (14) to capture the target compound in the column (14). Thereafter, wash water is introduced in the trap column (14). Then, the setting of a six-port valve (7) is changed and an on/off valve (6) is opened to introduce nitrogen gas through a supply-side passage (8) in the trap column (14). In this stage, the nitrogen gas is warmed by means of a heat-exchange block (10), and the trap column (14) is warmed via a column rack (15). Any water remaining in the trap column (14) is initially thrust upwards by the nitrogen gas, to be extruded from an exit edge (14b) and discharged through a discharge-side passage (20). Furthermore, any water adhering to adsorbent or the inner wall surface of the trap column (14) is quickly vaporized and carried away by the nitrogen gas. In this manner, any water remaining in the trap column (14) can be rapidly removed, so that no water will be included in an eluate in the subsequent stage where a solvent with a strong elution power is introduced into the trap column (14) to collect the eluate. Thus, the eluate is rapidly vaporized and dried, so that the target compound in solid forms can be efficiently collected.

摘要： The present invention relates to an optical transmission line enabling Raman amplification of an optical signal when pumping light is supplied thereto, a method of making this optical transmission line, and an optical transmission system using this optical transmission line. This optical transmission line is an optical transmission line enabling Raman amplification of an optical signal when pumping light is supplied thereto, wherein a region yielding the maximum value of Raman gain coefficient is separated from an end portion where the pumping light is supplied by a predetermined distance along a direction in which the pumping light advances. This optical transmission line can restrain the power of optical signal, at any point of the optical transmission line, from increasing to such an extent that optical Kerr effects occurs remarkably and from decreasing to such an extent that the SN ratio deteriorates greatly, and can fully secure the power of optical signal at the end point of the optical transmission line.

摘要： An optical switch according to this invention has a planar waveguide in which an optical path is formed. A trench is formed in the upper surface of this planar waveguide. A cantilevered movable member is mounted on the planar waveguide. A comb is formed in the end portion of this movable member. A mirror which intercepts light propagating on the optical path is fixed to the end of the movable member. An electrode opposing the movable member is formed on the planar waveguide. A comb is formed in that portion of this electrode, which opposes the comb of the movable member. The movable member and electrode are connected via a voltage source. When this voltage source generates electrostatic force between the movable member and electrode, the movable member bends, and the mirror moves along the bottom surface of the trench accordingly.

摘要： An optical signal, which is to become the subject of dispersion compensation, is split by optical combining/splitting unit 2, and each frequency component of the optical signal that is split is reflected by the corresponding reflective mirror 30 included in reflective mirror group 3 to apply a predetermined phase shift to the respective frequency components Each reflected frequency component is then combined using optical combining/splitting unit 2, to give dispersion compensated optical signal Furthermore, in regards to reflective mirror group 3, which is used to apply phase shift to each frequency component of an optical signal, each of the respective plurality of reflective mirrors 30 is made a movable mirror having a movable reflection position that reflects the frequency components. Through this, dispersion that develops in an optical signal may be compensated with favorable controllability and high accuracy. Therefore, the precision and controllability of dispersion compensation will become superior, and realized is a variable dispersion compensator having a miniaturized optical circuit, and an optical transmission system comprising such variable dispersion compensator,

摘要： A main optical path and an auxiliary optical path which are formed in a substrate are optically coupled to each other with a plurality of optical couplers, so as to constitute a Mach-Zehnder interferometer. By controlling the temperature regulation of main and auxiliary optical paths effected by heaters, a control unit regulates the transmissivity of light across an optical input end and an optical output end. Respective optical path lengths of the main and auxiliary optical paths are set so as to lower birefringence when optical loss becomes greater.
