Strechable crumpled graphene photodetector with plasmonically-enhanced photoresponsivity
Graphene has been widely explored for flexible, high-performance photodetectors due to its exceptional mechanical strength, broadband absorption, and high carrier mobility. However, the low stretchability and limited photoabsorption of graphene have restricted its applications in flexible and …

Waveguide Integrated Optoelectronics Using Two-Dimensional Materials
… The current state of waveguide integrated photodetectors and modulators is reviewed and provides a context for the work detailed in the following chapters. The first dual-function graphene photodetector and modulator is demonstrated in a simple geometry that allows simultaneous use of both …

Time-domain Modeling of Light Matter Interactions in Active Plasmonic Metamaterials
… for transparent conducting electrodes, and a graphene photodetector enhanced by a fractal plasmonic metasurface. In addition to this we also developed a multi-physics time-domain model to investigate the properties of a silver nanohole array coated with Rhodamine-101 dye. With accurate …
