ABSTRACT:
Disclosed is a method of adjusting a center channel wavelength of a group of channel wavelengths from of a plurality of modulated sources, integrated in a photonic integrated circuit (PIC), relative to the center of a wavelength passband of an optical combiner, such as an arrayed waveguide array (AWG), also integrated in the photonic integrated circuit (PIC) and optically coupled to outputs from the modulated sources.
