Abstract
An information acquiring device that acquires information on a measurement object includes: a dividing section that divides pulsed light having a center wavelength λc emitted from a light source into lights for a plurality of optical paths; waveguides provided in each of the optical paths; a multiplexing section that multiplexes lights emitted from the waveguides; and an information acquiring section that acquires information through detection of a light obtained by the multiplexing by the multiplexing section and applied to the object. In the information acquiring device, the waveguides provided in the optical paths, respectively are waveguides having different zero dispersion wavelengths, and the waveguides generate a plurality of wavelength-converted lights each having a center wavelength different from the center wavelength λc of the pulse light.
