D. Elvira, X. Hachair, Varun Verma, R. Braive, G. Beaudoin, I. Robert-Philip, I. Sagnes, Burm Baek, Sae Woo Nam, E Dauler, I. Abram, Martin Stevens, A. Beveratos
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

Time-resolved photoluminescence of lithographically defined quantum dots fabricated by electron beam lithography and wet chemical etching

Varun B. Verma, Martin J. Stevens, Kevin L. Silverman, Neville Dias, Akash Garg, James J. Coleman, Richard P. Mirin
We measure the time-resolved photoluminescence characteristics of a novel type of lithographically patterned quantum dot fabricated by electron beam lithography, wet chemical etching, and overgrowth of the barrier layers by metalorganic chemical vapor

Photon antibunching from a single lithographically defined InGaAs/GaAs quantum dot

Varun B. Verma, Martin J. Stevens, Kevin L. Silverman, Neville Dias, Akash Garg, James J. Coleman, Richard P. Mirin
We demonstrate photon antibunching from a single lithographically defined quantum dot fabricated by electron beam lithography, wet chemical etching, and overgrowth of the barrier layers by metalorganic chemical vapor deposition. Measurement of the second
