Abstract
A wavelength conversion device that obtains, from an input light, a wavelength-converted light with a wavelength shift by a wavelength shift amount of Δλ is disclosed. The device comprises first and second wavelength converters. The first wavelength convertor shifts a central wavelength of a first wavelength-converted light by a first wavelength shift amount of Δλ1 relative to a central wavelength of an input light. The second wavelength convertor shifts a central wavelength of a second wavelength-converted light by a second wavelength shift amount of Δλ2 relative to a central wavelength of the first wavelength-converted light. The first wavelength shift amount of Δλ1 and the second wavelength shift amount of Δλ2 satisfy Δλ1+Δλ2=Δλ.
