We demonstrate the use of periodically modulated Coulomb shifts in quantum dot (QD) transition energies to obtain differential reflection spectra of a photonic crystal nanocavity containing strongly coupled dots. Measured spectra isolate the change in the empty cavity optical reflectivity spectrum due to the presence of each dot. This technique permits the probing of coupled QD-cavity systems possessing cavity modes of arbitrary polarization, making it attractive for use in both cavity quantum electrodynamics studies and quantum information applications.
