In this paper, we present our approach on the realization of vertical coupling technology that has been verified for microlaser fabrication as well as for the realization of high Q resonators with 'loss-less' cavities based on InP. The concept is based on full wafer technology and provides the integration of an optical transparent passive bus waveguide vertically coupled to the active ring laser.
