    "abstract": "We observe large spontaneous emission rate modification of individual InAs\nQuantum Dots (QDs) in 2D a photonic crystal with a modified, high-Q single\ndefect cavity. Compared to QDs in bulk semiconductor, QDs that are resonant\nwith the cavity show an emission rate increase by up to a factor of 8. In\ncontrast, off-resonant QDs indicate up to five-fold rate quenching as the local\ndensity of optical states (LDOS) is diminished in the photonic crystal. In both\ncases we demonstrate photon antibunching, showing that the structure represents\nan on-demand single photon source with pulse duration from 210 ps to 8 ns. We\nexplain the suppression of QD emission rate using Finite Difference Time Domain\n(FDTD) simulations and find good agreement with experiment.",
