Quantum dynamics of confined modes of a metasurface
Quantum Photonic Devices, 2017Metasurfaces made of dielectric resonators exhibit electromagnetic surface modes analogous to surface plasmons. These modes possess a very small group velocity due to the weak coupling between the resonators. These modes can be used to reach the regime of strong coupling with a quantum resonator situated in the vicinity of the metasurface. We develop a

Dielectric metasurfaces for quantum weak measurements
Applied Physics Letters, 2017Metasurfaces have shown extraordinary abilities to manipulate the phase and polarization of light and thus hold great promise for applications in photonics and optoelectronics. Here, we propose a unique application of the dielectric metasurface for quantum weak measurements.

Quantum Pair Generation in Nonlinear Metasurfaces with Mixed and Pure Photon Polarizations.
Nano letters (Print)Metasurfaces are highly effective at manipulating classical light in the linear regime; however, effectively controlling the polarization of nonclassical light generated from nonlinear resonant metasurfaces remains a challenge.

A Multichannel Metasurface for Multiprotocol Quantum Key Distributions
Nano LettersMultiprotocol quantum key distribution (mQKD) enables users to flexibly select protocols for secure quantum communication, though achieving mQKD introduces considerable system complexity and resource demands. Here, we report the first realization of mQKD using a metasurface, which generates multiple hybrid states of photonic spin angular momentum (SAM)

Terahertz metasurface quantum cascade lasers
2016 International Conference on Optical MEMS and Nanophotonics (OMN), 2016We report THz quantum-cascade vertical-external-cavity surface-emitting-lasers (VECSELs) with up to 60 mW of power at 3.3 THz at 77 K. High quality, directive, near-diffraction limited, Gaussian beams are observed.

Computing Metasurface Enabled Quantum Phase Distillation
Nano LettersQuantum image distillation aims to extract the signal image from a mixture of the signal and noise images that are indistinguishable in terms of spectrum and polarization, a process that is unachievable with classical methods. However, in contrast to the amplitude image, phase distillation is challenging via direct spatial or temporal correlation of ...

Metasurface-Enabled On-Chip Quantum Entanglement
Conference on Lasers and Electro-Optics, 2017We report on on-chip quantum entanglement between two microscopically separated qubits by engineering their long-range interactions via a metasurface. The metasurface route to quantum state engineering opens a new paradigm for on-chip quantum technology.

Multipole and Metasurface Quantum Well Emitters
2019 IEEE Research and Applications of Photonics in Defense Conference (RAPID), 2019Semiconductor quantum wells underpin a great number of modern optoelectronics technologies. Here, we demonstrate directional photoluminescence arising from: 1) magnetic dipole transitions in layered two-dimensional hybrid organic-inorganic perovskite quantum wells and 2) phased array GaN quantum well metasurfaces.
