We demonstrate and characterize continuous wave chi((2)) sum-frequency generation in gallium phosphide photonic crystal nanocavities. We use two confined modes of the nanocavity in the wavelength range 1500-1600 nm to enhance conversion efficiency. Our results show that these nanocavities can serve as integrated light sources across a range of wavelengths, and are promising for on-chip upconversion of weak intensity telecommunication wavelengths signals to visible wavelengths.
