Obtaining a first drive condition of the wavelength tunable laser for lasing at a first wavelength from a memory;
A second drive condition for driving the wavelength tunable laser at the second wavelength with reference to the first drive condition and a wavelength difference between the first wavelength and a second wavelength different from the first wavelength. A second step of calculating
A third step of driving the tunable laser based on the second driving condition obtained by the second step,
In the second step, when the second wavelength is longer than the first wavelength, the temperature of the optical waveguide is always higher than the temperature of the optical waveguide indicated in the first driving condition. When the second driving condition is calculated under a high condition, and the second wavelength is shorter than the first wavelength, the temperature of the optical waveguide is the optical light indicated by the first driving condition. A method for controlling a wavelength tunable laser, wherein the second driving condition is calculated under a condition that is always lower than a temperature of the waveguide.
