We have studied how coupling together a 2 dimensional photonic crystal (2D PC), made in a SOI wafer, and a Bragg mirror could modify the light properties of the light emitted by the 2D PC. By finely tuning the distance separating the Bragg mirror and the 2D PC with a piezo-electric set-up, we have recorded a modulation of the extracted intensity as well as of the quality factor of the structure (Q)...
