Triply-Resonant Sum Frequency Conversion with Gallium Phosphide Ring Resonators
Alan D. Logan, Shivangi Shree, Srivatsa Chakravarthi +5
We demonstrate quasi-phase matched, triply-resonant sum frequency conversion in 10.6-um-diameter integrated gallium phosphide ring resonators. A small-signal, waveguide-to-waveguid…
Exciton spectroscopy and diffusion in MoSe2-WSe2 lateral heterostructures encapsulated in hexagonal boron nitride
Dorian Beret, Ioannis Paradisanos, Ziyang Gan +17
Chemical vapor deposition (CVD) allows lateral edge epitaxy of transition metal dichalcogenide heterostructures with potential applications in optoelectronics. Critical for carrier…
Capacitively-coupled and inductively-coupled excitons in bilayer MoS
Lukas Sponfeldner, Nadine Leisgang, Shivangi Shree +10
The interaction of intralayer and interlayer excitons is studied in a two-dimensional semiconductor, homobilayer MoS. It is shown that the measured optical susceptibility revea…
Room Temperature Micro-Photoluminescence Studies of Colloidal WS2 Nanosheets
André Philipp Frauendorf, André Niebur, Lena Harms +5
Wet-chemical syntheses for quasi two-dimensional (2D) transition metal dichalcogenides (TMDs) have emerged as promising methods for straightforward solution-processing of these mat…
Interlayer exciton mediated second harmonic generation in bilayer MoS2
Shivangi Shree, Delphine Lagarde, Laurent Lombez +10
Second harmonic generation (SHG) is a non-linear optical process, where two photons coherently combine into one photon of twice their energy. Efficient SHG occurs for crystals with…
Unveiling the optical emission channels of monolayer semiconductors coupled to silicon nanoantennas
Jean-Marie Poumirol, Ioannis Paradisanos, Shivangi Shree +13
Monolayers (MLs) of transition metal dichalcogenides (TMDs) such as WSe2 and MoSe2 can be placed by dry stamping directly on broadband dielectric resonators, which have the ability…
