摘要： The present invention relates to an optical fiber which has a structure for further increasing an FOM (=|dispersion|/loss) and which can be applied to a dispersion compensation module. The optical fiber is mainly composed of silica glass and has a core region including a center of an optical axis, a depressed region surrounding the core region, a ring region surrounding the depressed region, and a cladding region surrounding the ring region and doped with F. As compared with the refractive index of pure silica glass, a relative refractive index difference of the core region is greater than 2% but less than 3%, a relative refractive index difference of the depressed region is −1% or more but −0.5% or less, a relative refractive index difference of the ring region is 0.01% or more but 0.24% or less, and a relative refractive index difference of the cladding region is −0.3% or more but −0.1% or less. The FOM at the wavelength of 1550 nm is 250 ps/nm/dB or more.

摘要： The present invention relates to an analyzing apparatus and the like having a structure for enabling spectrometry and the like up to a longer frequency region while being excellent in practicality. The analyzing apparatus comprises a light source section and a light-detecting section. The light source section includes a seed light source emitting laser light, and a solid highly nonlinear optical fiber generating SC light in response to the input of the laser light, and thereby emitting the SC light as irradiation light to an object. The light-detecting section detects light to be detected from the object irradiated with the irradiation light. Here, the seed light source in the light source section emits pulsed light having a center wavelength within the range of 1.3 μm to 1.8 μm.
