Title: Higher-order photon correlations in pulsed photonic crystal nanolasers
Published: December 16, 2011
Abstract: We report on the higher-order photon correlations of a high-Β nanolaser under pulsed excitation at room temperature. Using a multiplexed four-element superconducting single-photon detector we measured g(n)(0) with n = 2,3,4. All orders of correlation display partially chaotic statistics, even at four times the threshold excitation power. We show that this departure from coherence and Poisson statistics is due to the quantum fluctuations associated with the small number of photons at the lasing threshold.
