We demonstrate the quality-factor (Q-factor) tuning of a photonic crystal nanocavity by thermo-optically bringing it into resonance with a different nearby cavity. Q-tuning of up to a factor 2 has been observed. The spontaneous emission rate of quantum dots in the cavity has also been measured, a lifetime depending on the spectral alignment of the two cavities has been found.
