C-band 160 Gbs-1 Zero-bias Graphene Photodetectors: Breaking the Responsivity-Bandwidth Trade-off by Heterostructure Engineering
Karuppasamy Pandian Soundarapandian, Alberto Montanaro, Ioannis Vangelidis +17
Graphene photodetectors offer ultrafast response and broadband operation, but their responsivity is typically limited by rapid hot-carrier cooling, leading to a trade-off between s…
Graphene Electro-Absorption Modulators for Energy-Efficient and High-Speed Optical Transceivers
M. Tiberi, A. Montanaro, C. Wen +19
The increasing demand for energy-efficient hardware for artificial intelligence (AI) and data centres requires integrated photonic solutions delivering optical transceivers with Tb…
High-speed Source-Device-Independent Quantum Random Number Generator on a Chip
Tommaso Bertapelle, Marco Avesani, Alberto Santamato +11
A wide range of applications require, by hypothesis, to have access to a high-speed, private, and genuine random source. Quantum Random Number Generators (QRNGs) are currently the…
