A self-written branched optical waveguide is formed. A laser beamfrom a laser source (not shown) is focused with a lensonto the face of incidenceof an optical fiber. The laser beam of an LPmode was emitted from the face of emergence, and 'bimodal' light intensity peaks were arranged in the horizontal direction (.A). A slide glasscoated with a photocurable resin gelwas placed horizontally (.B). A single linear cured materialwas formed as the LP-mode laser beam was emitted from the face of emergenceof the optical fiber(.C). A branch portionwas then formed at a distance L from the face of emergenceof the optical fiber, which was followed by the growth of two cylindrical cured materialsand. The two cylindrical cured materialsandwere linear branches, and formed an angle of about four degrees. An optical waveguidethus formed was composed of cured materials, and(.D).

Optical waveguide and method for manufacturing the same

To provide a biochip, a biochip manufacturing method, an electrophoresis method, and an electrophoresis apparatus, by which the detection accuracy may improve, there is a biochip introducing a sample in band form into a sample separation passage, by a means for reducing the band width of sample, at which the sample is before being introduced in the sample separation passage in band form. The band of sample supplied to the sample separation passage is compressed, and the expansion by diffusion may be prevented, thus the detection accuracy may improve.

Biochip and a manufacturing method of biochip

An optical recording method suited for recording a very small object or movement of a living organism such as a microorganism, which comprises irradiating an informative object set on or above a recording layer comprising a photosensitive material capable of undergoing a storable and detectable photochemical reaction, preferably a polymer material containing a photoreactive component capable of photoisomerization and having in the repeating unit thereof at least one group selected from a urethane group, a urea group, an amide group, a carboxyl group and a hydroxyl group, and recording a distribution of an optical near field generated from the informative object being irradiated on the photosensitive material as a photoreacting quantity of the photosensitive material.

Optical recording method, optical recording medium, and optical recording system

There is inserted between a light source and an input of an optical fiber a mode filter which changes the phase of light to be propagated continuously or discontinuously so as to convert guided modes of lower azimuthal number into those of higher numbers in a light transmitting system which employs a graded index optical fiber with a valley at the core-cladding boundary. This reduces the mode-delay differences for all modes including those which are close to cut off so that an optical communication system having a very wide bandwidth is obtained.
