The optical fiber preform fabricating method comprises a glass synthesis step for forming a glass region constituting at least a part of the core area of the optical fiber. The glass synthesis step includes a deposition step of depositing glass particles containing the Al-element inside the glass pipe by means of chemical vapor deposition, and a consolidation step of obtaining a transparent glass body from the glass soot body thus obtained. In other words, the deposition step synthesizes glass particles on the inside wall of a glass pipe by feeding raw material gas, in which the content ratio (O/Al) of the O-element and Al-element is 20 or less, into the glass pipe. Furthermore, the consolidation step obtains a transparent glass body from the glass soot body by heating the glass soot body. The transparent glass body that is formed in the consolidation step constitutes part of the core region.

摘要： The present invention relates to a long-life, low-power consumption infrared imaging system having a structure for realizing with a high reliability both the taking of an image of its surrounding environments and the detection of objects. The infrared imaging system comprises a light source section, an image pickup section, a processing section, and a monitor. For emitting SC light including a wavelength component in a near-infrared wavelength band as irradiation light, the light source section includes a seed light source emitting laser light, an optical fiber generating the SC light in response to the input of the laser light, and wavelength selecting means. The wavelength selecting means selectively limits the wavelength region of the irradiation light in accordance with imaging modes. In the mode for taking an image of a surrounding environment, the wavelength selecting means limits the irradiation light wavelength to a wavelength band excluding an absorption wavelength band of moisture and the like in the air. In the mode for detecting an object such as a frozen part on the road surface, on the other hand, the wavelength selecting means limits the irradiation light wavelength to an absorption wavelength band of water or ice.

摘要： The present invention relates to an optical gain waveguide having excellent gain flatness in C-band, and excellent tolerance against variations of a pumping light wavelength as well, and a method of controlling the same. The optical gain waveguide includes an optical waveguide region which is doped with Er element which can be pumped by irradiating pumping light with a wavelength of 976 nm or less, or a wavelength of 981 nm or more. A population inversion of Er is optimized so that a gain variation in the C-band becomes minimum, by the irradiation of the pumping light. At this time, a relative gain variation of the optical gain waveguide, which is defined by a peak gain value and a minimum gain value in the wavelength region of 1,530 nm to 1,560 nm becomes smaller than 11.5%. In addition, in the optical gain waveguide, a width of wavelength range producing the relative gain variation smaller than 11% is 36 nm or more.
