Zusammenfassung:A method of controlling the center wavelength of a wavelength sweeping laser and an apparatus for performing the same are disclosed. According to an embodiment, a central wavelength controller for controlling the center wavelength of a wavelength sweeping laser includes a thermistor for measuring the temperature of the wavelength sweeping laser and a controller for comparing the temperature with a reference temperature and controlling an output voltage to the wavelength sweeping laser. 파장 가변 레이저의 중심파장 제어 방법 및 이를 수행하는 장치가 개시된다. 일 실시예에 따른 파장 가변 레이저의 중심파장을 제어하기 위한 중심파장 제어 장치는 상기 파장 가변 레이저의 온도를 측정하는 서미스터와, 상기 온도와 기준 온도를 비교하여 상기 파장 가변 레이저로의 출력 전압을 제어하는 컨트롤러를 포함한다.
