Abstract
The frequency-stabilized laser in 1.5μm region is vital for high capacity dense wavelength division multiplexing(DWDM).The acetylene saturated-absorption frequency stabilization can be used to stabilize the frequency of lasers in 1.5μm region.A fiber grating external cavity laser diode(ECLD) was designed according to the method of frequency stabilization,in which a step motor was used to strain the fiber grating to tune the wavelength,and the power of light was modulated by modulating the injecting current.The effect of frequency stabilization was authenticated by experiment.
