Cryogenic photoluminescence imaging system for nanoscale positioning of single quantum emitters
Jin Liu, Macelo Davanco, Luca Sapienza +5
We report a photoluminescence imaging system for locating single quantum emitters with respect to alignment features. Samples are interrogated in a 4~K closed-cycle cryostat by a h…
Combined atomic force microscopy and photoluminescence imaging to select single InAs/GaAs quantum dots for quantum photonic devices
Luca Sapienza, Jin Liu, Jin Dong Song +4
We report on a combined photoluminescence imaging and atomic force microscopy study of single, isolated self-assembled InAs quantum dots (density <0.01 um^(-2) capped by a 95 nm Ga…
A heterogeneous III-V/silicon integration platform for on-chip quantum photonic circuits with single quantum dot devices
Marcelo Davanco, Jin Liu, Luca Sapienza +7
Photonic integration is an enabling technology for photonic quantum science, offering greater scalability, stability, and functionality than traditional bulk optics. Here, we descr…
Anderson localisation of visible light on a nanophotonic chip
Tom Crane, Oliver J. Trojak, Luca Sapienza
We demonstrate Anderson localisation of visible light on a chip and report quality factors exceeding highly engineered two-dimensional cavities. Our results reverse the trend, obse…
Magneto-optical spectroscopy of single charge-tunable InAs/GaAs quantum dots emitting at telecom wavelengths
Luca Sapienza, Rima Al-Khuzheyri, Adetunmise Dada +3
We report on the optical properties of single InAs/GaAs quantum dots emitting near the telecommunication O-band, probed via Coulomb blockade and non-resonant photoluminescence spec…
