Abstract :
An integrated optoelectronic device for the generation of tunable and narrow linewidth radio frequency (RF) signals is proposed, consisting of two DFB lasers that are external injected into a semiconductor ring laser (SRL). The three lasers achieve mutual injection and phase locking. The beating between the output optical spectral lines generates an electrical signal with narrow linewidth and high tunibility.
