We integrate resonant‐cavity light‐emitting diodes containing quantum dots onto substrates with giant piezoelectric response. Via strain, the energy of the photons emitted by the diode can be precisely controlled during electrical injection over a spectral range larger than 20 meV. Simultaneously, the exciton fine‐structure‐splitting and the biexciton binding energy can be tuned to the values required for entangled photon generation.
