摘要：This object aims to provide a wavelength-variable laser device which can perform wavelength switching without a grid hop and a wavelength switching method of the same. A wavelength-variable laser device (101) includes a semiconductor light amplifier (102) and a periodic wavelength selection filter (106). The wavelength-variable laser device (101) includes a phase control unit (111) which performs an open-loop control of a current applied to the semiconductor light amplifier (102) and a phase adjustment of a variable wavelength laser concurrently. Accordingly, dark tuning becomes possible.
