Fullwave Maxwell inverse design of axisymmetric, tunable, and multi-scale multi-wavelength metalenses
Rasmus E. Christiansen, Zin Lin, Charles Roques Carmes +5
We demonstrate new axisymmetric inverse-design techniques that can solve problems radically different from traditional lenses, including \emph{reconfigurable} lenses (that shift a…

Waveguide-integrated van der Waals heterostructure photodetector at telecom band with high speed and high responsivity
Nikolaus Flöry, Ping Ma, Yannick Salamin +5
Intensive efforts have been devoted to exploit novel optoelectronic devices based on two-dimensional (2D) transition-metal dichalcogenides (TMDCs) owing to their strong light-matte…

Plasmonically enhanced graphene photodetector featuring 100 GBd, high-responsivity and compact size
Ping Ma, Yannick Salamin, Benedikt Baeuerle +5
Graphene has shown great potentials for high-speed photodetection. Yet, the responsivities of graphene-based high-speed photodetectors are commonly limited by the weak effective ab…
