TL;DR: A flow for the integration of graphene in photonics circuits relies on chemical vapor deposition of single layer graphene (SLG) matrices comprising up to ∼12000 individual single crystals, grown to match the geometrical configuration of the devices in the photonic circuit.

TL;DR: This work reports compact, scalable, high-performance, waveguide integrated graphene-based photodetectors (GPDs) for telecom and datacom applications, not affected by dark current, and are the fastest GPDs operating with zero dark current.

TL;DR: A chemical vapour deposition graphene photodetector based on the photo-thermoelectric effect, integrated on a silicon waveguide, providing frequency response >65 GHz and optimized to be interfaced to a 50 Ω voltage amplifier for direct voltage amplification.

TL;DR: In this paper, a C-band double layer graphene electro-absorption modulator on a passive SOI platform showing 29GHz 3dB-band with and NRZ eye-diagrams extinction ratios ranging from 17 dB at 10 Gb/s to 13 dB at 50 Gb /s.

TL;DR: In this paper, an optimized photo-thermo-electric (PTE) based photodetector with flat frequency response up to 65 GHz was proposed for high speed datacom and telecom applications.
