We report on anisotropic strain induced fine-tuning of semiconductor quantum dots (QDs) embedded into a photonic crystal nanocavity. Due to a complete removal of the sample substrate we achieve large spectral tuning ranges of up to 5.83 meV for the QD emission lines, which is sufficient to readily establish spectral resonance with the high Q cavity mode. When the QD emission lines are swept through the mode, we observe an enhancement of the QD emission in this weakly coupled QD-resonator system.
