Title:
WAVELENGTH-TUNABLE LIGHT SOURCE DEVICE AND WAVELENGTH CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/084673
Kind Code:
A1
Abstract:
Since oscillation wavelengths are unstable in wavelength-tunable light sources, this wavelength-tunable light source device comprises: an optical amplification means; an optical waveguide means provided with a wavelength-tunable filter; a mounting means on which the optical amplification means and the optical waveguide means are mounted; and a control means which controls the optical waveguide means and the mounting means. The control means controls the temperature of the mounting means such that the wavelength of a ripple caused by internal reflection matches a predetermined wavelength.
