Passive harmonic mode-locking by mode selection in Fabry-Perot diode lasers with patterned effective index
D. Bitauld, S. Osborne, S. O'Brien
We demonstrate passive harmonic mode-locking of a quantum well laser diode designed to support a discrete comb of Fabry-Perot modes. Spectral filtering of the mode spectrum was ach…
Superconducting parallel nanowire detector with photon number resolving functionality
F. Marsili, D. Bitauld, A. Fiore +9
We present a new photon number resolving detector (PNR), the Parallel Nanowire Detector (PND), which uses spatial multiplexing on a subwavelength scale to provide a single electric…
Demonstration of Free-space Reference Frame Independent Quantum Key Distribution
J. Wabnig, D. Bitauld, H. W. Li +3
Quantum key distribution (QKD) is moving from research laboratories towards applications. As computing becomes more mobile, cashless as well as cardless payment solutions are intro…
High performance NbN nanowire superconducting single photon detectors fabricated on MgO substrates
F. Marsili, D. Bitauld, A. Fiore +5
We demonstrate high-performance nanowire superconducting single photon detectors (SSPDs) on ultrathin NbN films grown at a temperature compatible with monolithic integration. NbN f…
Calibration and High Fidelity Measurement of a Quantum Photonic Chip
H. W. Li, J. Wabnig, D. Bitauld +5
Integrated quantum photonic circuits are becoming increasingly complex. Accurate calibration of device parameters and detailed characterization of the prepared quantum states are c…
Enhanced spontaneous emission in a photonic crystal light-emitting diode
M. Francardi, L. Balet, A. Gerardino +5
We report direct evidence of enhanced spontaneous emission in a photonic crystal (PhC) light-emitting diode. The device consists of p-i-n heterojunction embedded in a suspended mem…
