Spontaneous emission enhancement in micropatterned GaN

With two interfering pulses from the fourth harmonic of a Nd–YAG laser we burnt a periodic lattice structure into the surface of GaN thin films. The lattice period of this permanent grating could be controlled between less than one and several tens of microns. Above the decomposition threshold, nitr...
