A room-temperature moiré interlayer exciton laser
Qiaoling Lin, Hanlin Fang, Yuanda Liu +10
Moiré superlattices in van der Waals heterostructures offer highly tunable quantum systems with emergent electronic and excitonic properties such as superconductivity, topological…
Valley-exchange coupling probed by angle-resolved photoluminescence
Joshua J. P Thompson, Samuel Brem, Hanlin Fang +7
The optical properties of monolayer transition metal dichalcogenides are dominated by tightly-bound excitons. They form at distinct valleys in reciprocal space, and can interact vi…
Criteria for deterministic single-photon emission in two-dimensional atomic crystals
Joshua J. P. Thompson, Samuel Brem, Hanlin Fang +4
The deterministic production of single-photons from two dimensional materials promises to usher in a new generation of photonic quantum devices. In this work, we outline criteria b…
Room temperature nanocavity laser with interlayer excitons in 2D heterostructures
Yuanda Liu, Hanlin Fang, Abdullah Rasmita +7
Atomically thin layered two dimensional (2D) material has provided a rich library for both fundamental research and device applications. One of the special advantages is that, band…
Fano resonance lineshapes in a waveguide-microring structure enabled by an air-hole
Linpeng Gu, Liang Fang, Hanlin Fang +5
We propose and demonstrate, by simply inserting an air-hole in the waveguide side-coupling with a microring resonator (MRR), the transmission spectrum presents Fano lineshapes at a…
Room temperature interlayer exciton valley polarization and valley Hall effect
Zumeng Huang, Yuanda Liu, Kévin Dini +5
For monolayer transition metal chalcogenides (TMDs), electrons and excitons in different valleys can be driven to opposite directions by the Berry curvature, serving as a valley-de…
Second harmonic and sum-frequency generations from a silicon metasurface integrated with a two-dimensional material
Qingchen Yuan, Liang Fang, Hanlin Fang +5
Silicon-based nonlinear metasurfaces were implemented only with third-order nonlinearity due to the crystal centrosymmetry and the efficiencies are considerably low, which hinders…
A compact structure for realizing Lorentzian, Fano and EIT resonance lineshapes in a microring resonator
Linpeng Gu, Hanlin Fang, Juntao Li +4
Microring resonators, as a fundamental building block of photonic integrated circuits, have been well developed into numerous functional devices, whose performances are strongly de…
Multiple optical frequency-conversions in few-layer GaSe assisted by a photonic crystal cavity
Liang Fang, Qingchen Yuan, Hanlin Fang +6
While two-dimensional (2D) materials have intriguing second-order nonlinearities with ultrahigh coefficient and electrical tunability, their atomic layer thicknesses hinder explora…
1305 nm MoTe2-on-silicon Laser
Hanlin Fang, Jin Liu, Hongji Li +6
The missing piece in the jigsaw of silicon photonics is a light source that can be easily incorporated into the standard silicon fabrication process. Recent advances in the develop…
Efficient silicon metasurfaces for visible light
Zhenpeng Zhou, Juntao Li, Rongbin Su +9
Dielectric metasurfaces require high refractive index contrast materials for optimum performance. This requirement imposes a severe restraint; devices have either been demonstrated…
