Wafer-scale integration of graphene-based photonic devices
Marco A. Giambra, Vaidotas Mišeikis, Sergio Pezzini +7
Graphene and related materials can lead to disruptive advances in next generation photonics and optoelectronics. The challenge is to devise growth, transfer and fabrication protoco…
Ultrafast, Zero-Bias, Graphene Photodetectors with Polymeric Gate Dielectric on Passive Photonic Waveguides
Vaidotas Mišeikis, Simone Marconi, Marco A. Giambra +15
We report compact, scalable, high-performance, waveguide integrated graphene-based photodetectors (GPDs) for telecom and datacom applications, not affected by dark current. To expl…
Synthesis of large-area rhombohedral few-layer graphene by chemical vapor deposition on copper
Chamseddine Bouhafs, Sergio Pezzini, Neeraj Mishra +6
Rhombohedral-stacked few-layer graphene (FLG) has been receiving an ever-increasing attention owing to its peculiar electronic properties that could lead to enticing phenomena such…
Photo Thermal Effect Graphene Detector Featuring 105 Gbit s-1 NRZ and 120 Gbit s-1 PAM4 Direct Detection

The challenge of next generation datacom and telecom communication is to increase the available bandwidth while reducing the size, cost and power consumption of photonic integrated…
Graphene Plasmonic Fractal Metamaterials for Broadband Photodetectors
Francesco De Nicola, Nikhil Santh Puthiya Purayil, Vaidotas Miŝeikis +6
Metamaterials have recently established a new paradigm for enhanced light absorption in state-of-the-art photodetectors. Here, we demonstrate broadband, highly efficient, polarizat…
High-speed double layer graphene electro-absorption modulator on SOI waveguide
Marco A. Giambra, Vito Sorianello, Vaidotas Miseikis +6
We report on a C-band double layer graphene electro-absorption modulator on a passive SOI platform showing 29GHz 3dB-bandwith and NRZ eye-diagrams extinction ratios ranging from 1.…
30-twisted bilayer graphene quasicrystals from chemical vapor deposition
Sergio Pezzini, Vaidotas Miseikis, Giulia Piccinini +8
The artificial stacking of atomically thin crystals suffers from intrinsic limitations in terms of control and reproducibility of the relative orientation of exfoliated flakes. Thi…
