Abstract: The present invention relates to an optical wavelength multiplexing and dividing device of an array waveguide type diffraction lattice, which is capable of separating and picking up wavelength-multiplexed signals of various wavelengths, which are used in optical transmissions. An input side slab waveguide (3), a plurality of juxtaposed array waveguides (4), an output side slab waveguide (5) and a plurality of optical output waveguides (6) are connected, in order, to the outgoing sides of a plurality of optical input waveguides (2), thereby forming a waveguide pattern. The array waveguides (4) are formed so as to have lengths different from each other to cause the phases of individual lights to be deviated after propagating through the respective array type waveguides (4), wherein different lights as per wavelength are condensed at the incident ends (7) of optical output waveguides 6 by passing through the output side slab waveguides (5) and are outputted through the optical output waveguides (6). The incident ends (7a) of the optical output waveguides (6) are provided at a light condensing predicted position of lights of the respective wavelengths where the lights are predicted to be condensed through the output side slab waveguide (5), and the incident ends (7b) of the optical output waveguides (6) are provided at a light condensing prediction corrected position where the light condensing position is shifted with respect to the light condensing predicted position.

Abstract: Provided herein is an elementary analysis apparatus allowing size and weight reduction and capable of performing atomic adsorption spectrometry by an electrothermal method and of forming plasma without using a gas. A sample is supplied from a liquid feed portion through a flow channel to an atomizing portion, and a voltage is applied between electrodes. When the voltage is applied to the electrodes, electric current and electric field are concentrated in the atomizing portion and bubbles are generated to cause a plasma in the bubbles, and element in the sample is atomized by the plasma. Light that irradiates the atomizing portion from a light source and is transmitted therethrough is received, for example, by an optical fiber or the like and split by a spectrophotometer. The amount of the split light is detected by a detector and analyzed by a computer.

Abstract: Disclosed is a wavelength multiplexing module which provides stable multiplexed output power. The wavelength multiplexing module comprises a plurality of pumping sources for outputting lights of different wavelengths, and a wavelength multiplexer for multiplexing the lights output from the pumping sources. The wavelength multiplexer is provided with optical input sections for respectively receiving the lights output from the pumping sources. Respectively provided between the optical input sections and the pumping sources are depolarizers each of which causes a degree of polarization of the light output from an associated one of the pumping sources to approach zero. Each depolarizer has two polarization-maintaining optical fibers connected in series on an optical path in such a way that primary optic axes of the polarization-maintaining optical fibers obliquely intersect each other.
