A multi-wavelength distributed Bragg reflector (DBR) laser diode is provided including front and rear DBR sections and a plurality of dedicated tuning signal control nodes. The front DBR section includes a plurality of front wavelength selective grating sections defining a plurality of distinct grating periodicities lambda1*, lambda2* . . . corresponding to distinct Bragg wavelengths lambdaS1*, lambdaS2* . . . . The rear DBR section comprises a plurality of rear wavelength selective grating sections defining a plurality of distinct grating periodicities lambda1, lambda2 . . . corresponding to distinct Bragg wavelengths lambdaS1, lambdaS2 . . . . The tuning signal control nodes are associated with corresponding front wavelength selective grating sections, rear wavelength selective grating sections, or both, such that tuning signals applied to one or more of the dedicated tuning signal control nodes spectrally aligns select Bragg wavelengths lambdaS1*, lambdaS2* . . . of the front DBR section with a selected distinct Bragg wavelengths lambdaS1, lambdaS2 . . . of the rear DBR section. |
