High-responsivity graphene photodetectors integrated on silicon microring resonators
Simone Schuler, Jakob E. Muench, Alfonso Ruocco +9
Graphene integrated photonics provides several advantages over conventional Si photonics. Single layer graphene (SLG) enables fast, broadband, and energy-efficient electro-optic mo…
Graphene photodetector integrated on a photonic crystal defect waveguide
Simone Schuler, Daniel Schall, Daniel Neumaier +4
We present a graphene photodetector for telecom applications based on a silicon photonic crystal defect waveguide. The photonic structure is used to confine the propagating light i…
Device physics of van der Waals heterojunction solar cells
Marco M. Furchi, Florian Höller, Lukas Dobusch +3
Heterostructures based on atomically thin semiconductors are considered a promising emerging technology for the realization of ultrathin and ultralight photovoltaic solar cells on…
Thermal light emission from monolayer MoS2
Lukas Dobusch, Simone Schuler, Vasili Perebeinos +1
Because of their strong excitonic photoluminescence (PL) and electroluminescence (EL), together with an excellent electronic tunability, transition metal dichalcogenide (TMD) semic…
Controlled generation of a pn-junction in a waveguide integrated graphene photodetector
Simone Schuler, Daniel Schall, Daniel Neumaier +5
With its electrically tunable light absorption and ultrafast photoresponse, graphene is a promising candidate for high-speed chip-integrated photonics. The generation mechanisms of…
