摘要： An object of this invention is to provide a mode field diameter conversion optical fiber which can be processed in a short period of time to have a reduced mode field diameter at a desired portion thereof. The optical fiber according to this invention comprises a core of silica glass having a residual tensile stress, and a cladding surrounding the core and having a lower refractive index than that of the core. The desired portion is heated to relax the residual tensile stress in the core, whereby the optical fiber has a reduced mode field diameter at the desired portion.

摘要： An optical isolator not dependent on the plane of polarization of an incident beam and does not allow the plane of polarization to change on the outgoing side. The optical isolator comprises a first parallel flat double refractive crystal substance; a first Faraday rotor for rotating the plane of polarization of a beam; a second parallel flat double refractive crystal substance; a second Faraday rotor for rotating the plane of polarization in a direction opposite to that in which said first Faraday rotor rotates the plane of polarization; a third parallel flat double refractive substance; a fourth parallel flat double refractive substance; and permanent magnets for magnetizing the Faraday rotor and second Faraday rotors. Since a pair of Faraday rotors for rotating the plane of polarization in opposite directions, the plane of polarization on the incident side does not change on the outgoing side.

摘要： A method for manufacturing a fiber-optic collimator which comprises the steps of projecting a beam of light, emerging outwardly from an optical fiber, through a lens onto a planar reflecting medium so as to reflect therefrom, causing the reflected beam of light to enter the fiber through the lens, and adjusting a relationship in position between the lens and the fiber such that the intensity of the reflected beam of light entering the fiber attains a maximum value. The lens and the fiber are then fixed in position when an indication is provided that the intensity of the reflected beam of light has attained the maximum value.

摘要： Collection containers (17) are heated by head conduction from a container rack (18) with a heater (19) as the heat source. When an eluting solvent is supplied into a trap column (7) by a pump (5), an eluate containing a target compound exiting from the column (7) flows through a preparative separation passage (13) and drips from a solution nozzle (13a), and this solution is separated into fine droplets by a gas stream blowing from a gas ejection nozzle (15a). When a droplet touches an inner wall of the container (17), the volatile solvent immediately vaporizes, leaving the target compound precipitated in solid forms on the inner wall. Thus, the process of vaporizing and drying the eluate to collect the target compound is completed within a short period of time. This process can be performed online and hence is suitable for laborsaving.

摘要： After a target compound is captured by an adsorbent within a trap column (7) held by a column rack (8) in a substantially vertical position and the column is filled with water to wash its inside, dichloromethane is slowly introduced from an inlet end (7a) on the lower side by a pump (5). The water within the trap column (7) is pushed upward by dichloromethane and exits from an outlet end (7b), to be disposed of via a two-way selector valve (12) and a disposal passage (14). Dichloromethane elutes the captured target compound. Therefore, when the eluate, which initially consists of water, changes via an emulsion to dichloromethane, the eluate contains an adequately high concentration of target compound. At this point, the two-way valve (12) is switched to a preparative separation passage (13). As a result, a solution that is adequately free from water and yet contains the target compound can be collected into a collection container (17), and the target compound in solid forms can be quickly obtained.

摘要： An optical transmission path in a Raman gain module (1) for transmitting signal light input from an input terminal (1a) and Raman-amplifying the signal light by pumping light supplied from pumping light source units (21, 22) is formed by connecting in series two Raman amplification optical fibers (11, 12) having different wavelength dispersion values. According to this arrangement, wavelength dispersion in the amplifier module (1) can be controlled using, e.g., the combination of the wavelength dispersion values of the Raman amplification optical fibers (11, 12). Hence, accumulation of dispersion into signal light and signal light transmission in an almost zero dispersion state are prevented, and degradation in signal light transmission quality due to the nonlinear optical effect is suppressed.
摘要翻译：拉曼增益模块（1）中的用于传输从输入端子（1a）输入的信号光并通过泵浦从泵浦光源单元（21,22）提供的光来对信号光进行拉曼放大的光传输路径是通过连接具有不同波长色散值的两个拉曼放大光纤（11,12）。根据这种布置，可以使用例如拉曼放大光纤（11,12）的波长色散值的组合来控制放大器模块（1）中的波长色散。因此，防止了色散在信号光中的积聚和几乎为零色散状态的信号光传输，并且抑制了由于非线性光学效应引起的信号光传输质量的劣化。
