Abstract
In this paper, we propose a new wavelength locking structure which uses the Michelson interferometer equipped with a movable arm. The proposed one consists of LD driver, Michelson interferometer, automatic temperature controller, automatic power controller, and signal processor. This structure can provide the wavelength locking capability of a resolution below 0.0005nm(=62.4MHz) and cope easily with an external environment variation using movable arm of Michelson interferometer to give a good stability.
