摘要： A photoelectric conversion unit in which efficiency of optical coupling and stability of mechanical coupling improve is obtained.The photoelectric conversion unit includes a light density conversion element 11 which changes at an output end face the density of light that has impinged on an incident end face and outputs the light, and a photoelectric conversion element 13. The photoelectric conversion element 13 is arranged closely to a high light-density side of the light density conversion element 11, and integrated with this light density conversion element 11. The photoelectric conversion element 13 can be a solar cell or a light emission medium. In the light density conversion element 11, it is preferable that a refractive index profile in the radial direction in a section becomes a square distribution. Further, the light density conversion element 11 uses silica glass in a base member, and by changing the addition amount of impurity added in this glass, a refractive index profile is formed.

摘要： An optical fiber and a broadband light source that can generate SC light having a broader bandwidth. A broadband light source 1 is equipped with a seed light source 11 and an optical fiber 12. The seed light source 11 outputs light having a central wavelength in the wavelength range of 1500 nm to 1650 nm. The optical fiber 12 outputs supercontinuum light a result of input of the light output from the seed light source. The optical fiber 12, which has a zero dispersion wavelength in the wavelength range of 1300 nm to 1500 nm and an effective area of 12 μm2 or less at the central wavelength, outputs supercontinuum light having a wavelength bandwidth expanded to 1000 nm or more.
