The optical coupling of guided modes in a GaP waveguide to nitrogen-vacancy

centers in diamond was demonstrated. The electric field penetration into diamond

and the loss of the guided mode were measured. The results indicate that the GaPdiamond

system could be useful in realizing coupled microcavity- nitrogenvacancy

devices for quantum information processing in diamond.
