Selective area growth (SAG) technology has been added to an established InP monolithic integration platform to fabricate arrays of multi-wavelength distributed feedback (DFB) lasers. The local epitaxy growth rate is controlled by the SiO2 mask width, and different quantum well (QW) thicknesses can be obtained in one run. The laser wavelengths span from 1447 nm to 1602 nm. The DFB lasers may include...
