Abstract
A broadband optical spectrum generating apparatusincludes a ultrashort pulsed fiber laserthat generates pulsed light having a pulse width in the unit of picosecond to femtosecond, and broadband optical spectrum-generating optical fibersthat are connected with the ultrashort pulse fiber laservia a lensand have characteristics of normal dispersion, that is, a nonlinear coefficient of not less than 10 [Wkm] and a magnitude of wavelength dispersion of not greater than a value 0 [ps/km/nm] with regard to a wavelength of the pulsed light. The resulting output is super continuum that is widely broadened to a wavelength band of 1400 nm to 1750 nm and is chirped to a linear characteristic.
