Abstract :
This paper presents the theoretical and experimental results of an injection-locked laser (ILL) device constructed by the MEMS technology to provide a wavelength-stabilized laser source for the applications of accurate time keeping. The device mainly consists of a MEMS tunable laser and a FP laser chip by a scheme of external injection. The combination of the injection locking and the MEMS technology produces a stabilized wavelength (> plusmn0.001 nm) at a small size (3 mm times 2 mm times 0.6 mm); both are crucial for portable atomic clocks
