A monolithic dual-wavelength DFB laser array based on sidewall gratings and a novel modulation of the grating coupling coefficient is proposed demonstrated experimentally.The distribution along cavity modulated by changing alignment between two sidewalls.The frequency difference lasing modes can be length recess depth.A series microwave signals in range 50 GHz to 59 observed after beating optical lines photodetector.The measured linewidths are 250 kHz 850 when 1200 μm 1000 μm, respectively.
