Complete Coherent Control of a Quantum Dot Strongly Coupled to a Nanocavity
Constantin Dory, Kevin A. Fischer, Kai Müller +6
Strongly coupled quantum dot-cavity systems provide a non-linear configuration of hybridized light-matter states with promising quantum-optical applications. Here, we investigate t…
Self-homodyne measurement of a dynamic Mollow triplet in the solid state
Kevin A. Fischer, Kai Müller, Armand Rundquist +6
The study of light-matter interaction at the quantum scale has been enabled by the cavity quantum electrodynamics (CQED) architecture, in which a quantum two-level system strongly…
Hybrid Group IV Nanophotonic Structures Incorporating Diamond Silicon-Vacancy Color Centers
Jingyuan Linda Zhang, Hitoshi Ishiwata, Thomas M. Babinec +13
We demonstrate a new approach for engineering group IV semiconductor-based quantum photonic structures containing negatively charged silicon-vacancy (SiV) color centers in diam…
Ge Microdisk with Lithographically-Tunable Strain using CMOS-Compatible Process
David S. Sukhdeo, Jan Petykiewicz, Shashank Gupta +6
We present germanium microdisk optical resonators under a large biaxial tensile strain using a CMOS-compatible fabrication process. Biaxial tensile strain of ~0.7% is achieved by m…
Direct Bandgap Light Emission from Strained Ge Nanowires Coupled with High-Q Optical Cavities
Jan Petykiewicz, Donguk Nam, David S. Sukhdeo +5
A silicon-compatible light source is the final missing piece for completing high-speed, low-power on-chip optical interconnects. In this paper, we present a germanium-based light e…
Inverse design and demonstration of a compact and broadband on-chip wavelength demultiplexer
Alexander Y. Piggott, Jesse Lu, Konstantinos G. Lagoudakis +3
Integrated photonic devices are poised to play a key role in a wide variety of applications, ranging from optical interconnects and sensors to quantum computing. However, only a sm…
Towards on-chip generation, routing and detection of non-classical light
Fabian Flassig, Michael Kaniber, Günther Reithmaier +5
We fabricate an integrated photonic circuit with emitter, waveguide and detector on one chip, based on a hybrid superconductor-semiconductor system. We detect photoluminescence fro…
Ultra-Low Threshold Monolayer Semiconductor Nanocavity Lasers
Sanfeng Wu, Sonia Buckley, John R. Schaibley +8
Engineering the electromagnetic environment of a nanoscale light emitter by a photonic cavity can significantly enhance its spontaneous emission rate through cavity quantum electro…
