Fabrication of low-loss III-V Bragg-reflection waveguides for parametric down-conversion
Hannah Thiel, Marita Wagner, Bianca Nardi +8
Entangled photon pairs are an important resource for quantum cryptography schemes that go beyond point-to-point communication. Semiconductor Bragg-reflection waveguides are a promi…
Difference-frequency generation in an AlGaAs Bragg-reflection waveguide using an on-chip electrically-pumped quantum dot laser
A. Schlager, M. Götsch, R. J. Chapman +7
Nonlinear frequency conversion is ubiquitous in laser engineering and quantum information technology. A long-standing goal in photonics is to integrate on-chip semiconductor laser…
Optical Thouless conductance and level-spacing statistics in two-dimensional Anderson localizing systems
Sandip Mondal, Randhir Kumar, Martin Kamp +1
We experimentally investigate spectral statistics in Anderson localization in two-dimensional amorphous disordered media. Intensity distributions captured over an ultrabroad wavele…
Discrepant transport characteristics under Anderson localization at the two limits of disorder
Randhir Kumar, Sandip Mondal, M. Balasubrahmaniyam +2
Anderson localization is a striking phenomenon wherein transport of light is arrested due to the formation of disorder-induced resonances. Hitherto, Anderson localization has been…
Observation of the transition from lasing driven by a bosonic to a fermionic reservoir in a GaAs quantum well microcavity
S. Brodbeck, H. Suchomel, M. Amthor +4
We show that, by monitoring the free carrier reservoir in a GaAs-based quantum well microcavity under nonresonant pulsed optical pumping, lasing supported by a fermionic reservoir…
Circularly polarized lasing in chiral modulated semiconductor microcavity with GaAs quantum wells
A. A. Demenev, V. D. Kulakovskii, C. Schneider +7
We report the elliptically, close to circularly polarized lasing at and 1.522 eV from an AlAs/AlGaAs Bragg microcavity with 12 GaAs quantum wells in the active regi…
