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…
Electronic-Photonic Interface for Multiuser Optical Wireless Communication
Youngin Kim, Laurenz Kulmer, Jae-Yong Kim +3
We demonstrate an electronic-photonic (EP) interface for multiuser optical wireless communication (OWC), consisting of a multibeam optical phased array (MBOPA) along with co-integr…
Barium Titanate and Lithium Niobate Permittivity and Pockels Coefficients from MHz to Sub-THz Frequencies
Daniel Chelladurai, Manuel Kohli, Joel Winiger +7
The Pockels effect is essential for controlling optical signals at the highest speeds, particularly for electro-optic modulators in photonic integrated circuits. Lithium niobate (L…
High-Speed Graphene-based Sub-Terahertz Receivers enabling Wireless Communications for 6G and Beyond
Karuppasamy Pandian Soundarapandian, Sebastián Castilla, Stefan M. Koepfli +12
In recent years, the telecommunications field has experienced an unparalleled proliferation of wireless data traffic. Innovative solutions are imperative to circumvent the inherent…
