We fabricate low-loss AlGaAs Bragg-reflection waveguides for the creation of telecom wavelength photon pairs via parametric down-conversion. These photon pairs are used in a hybrid on-chip time-bin entanglement scheme.

We present the first experimental demonstration of a topological insulator VCSEL array. Our laser consists of 30 emitters, emitting in a single frequency, displaying interference proving that the emitters act as a single laser.

We investigate the efficient generation of photons in broadband deterministic quantum dot-micropillar cavities. The quantum-dot cavity coupling leads to Purcell factors above 2 for both exciton and biexciton photons.

We observe experimentally collective lasing of a topological mode in a vertical-cavity surface-emitting laser (VCSEL) array. The array is comprised of pillar-shaped VCSELs in a crystalline model geometry and is optically pumped.

We report frequency conversion of single photons from a quantum dot using four-wave-mixing Bragg scattering in a Si3N microring. We measure an on-chip conversion efficiency >10%, and frequency-converted light that is antibunched with g(2)(0)

Efficient fiber-coupled single photon sources are demonstrated based on phase-matched coupling between microfiber and linear photonic crystal cavity. Detected count rate over 1 MHz and fiber collection efficiency of 40% are obtained with Purcell enha

We experimentally and theoretically investigate injection locking of high-β microlasers and show simultaneous stationary oscillation synchronized to the external signal and at the solitary frequency, where their macroscopic counterparts exhibit perf
