Abstract
The present invention relates to a method for manufacturing a plurality of semiconductor photonic integrated circuit comprising at least a laser and a modulator connected optically to one another. Each laser and modulator has a waveguide layer being implemented on a single substrate, where said modulator is formed by use of a selective area growth technique. By providing modulator masking parts with selectable width to compensate a difference in band-gap energy in the waveguide layer between the laser and the modulator a approximate uniform difference in band-gap energy between the optically connected laser and modulator may be obtained.
