Abstract
The present invention relates to a wavelength locking structure for a tunable laser and a wavelength locking method for a tunable laser. According to the present invention, since it is possible to use only one element for measuring the intensity of light, the number of parts is reduced in comparison to methods of the related art, so it is possible to perform wavelength locking economically with a down-sized structure.
