Abstract

A method of emitting wavelength-swept light includes controlling either one or both of magnitudes and on/off timings of currents to be applied to a first gain medium of a first optical generator and a second gain medium of a second optical generator to control an intensity and a wavelength region of each of first wavelength-swept light and second wavelength-swept light; generating the first wavelength-swept light having a first center wavelength based on the current applied to the first gain medium of the first optical generator; generating the second wavelength-swept light having a second center wavelength based on the current applied to the second gain medium of the second optical generator; and emitting output wavelength-swept light by coupling the first wavelength-swept light and the second wavelength-swept light.
