We present here two critical elements for 3D integrated photonics. Based on large area high quality factor photonic crystal cavities, high power single mode surface emitting lasers can be obtained with very narrow linewidths. Additionally, with dispersion control and Dirac band lattice design, fast full 2p phase control is possible in these photonic crystal cavities. The combination and integration of laser and phase control enables 3D integrated photonic functions with high beam and spectral quality lasers, laser beam front control, and beam steering capabilities.
