We demonstrate dynamic control of spontaneous emission of quantum rods embedded in a large-area (∼0.8 cm2) triangular lattice 2D photonic crystal, which exhibits unusual multirefringence. Upon rotating the photonic crystal azimuthally, the photoluminescence of the embedded quantum rods increases abruptly at certain angles. Numerical simulations confirm that anisotropy along preferred directions, resulting in multirefringence of the crystal, is the underlying reason for the observed effect.
