  We discuss the progress in integration of nanodiamonds with photonic devices
for quantum optics applications. Experimental results in GaP, SiO2 and
SiC-nanodiamond platforms show that various regimes of light and matter
interaction can be achieved by engineering color center systems through hybrid
approaches. We present our recent results on the growth of color center-rich
nanodiamond on prefabricated 3C-SiC microdisk resonators. These hybrid devices
achieve up to five-fold enhancement of diamond color center light emission and
can be employed for integrated quantum photonics.
