Ultra-Efficient DC-gated all-optical graphene switch
Mohammed Alaloul, Khalil As'ham, Haroldo T. Hattori +1
The ultrafast response and broadband absorption of all-optical graphene switches are highly desirable features for on-chip photonic switching. However, because graphene is an atomi…
On-chip low-loss all-optical MoSe modulator
Mohammed Alaloul, Jacob B Khurgin, Ibrahim Al-Ani +4
Monolayer transition metal dichalcogenides (TMDCs), like MoS, MoSe, WS, and WSe, feature direct bandgaps, strong spin-orbit coupling, and exciton-polariton interact…
Dynamic Terahertz Beam Steering Based on Graphene Metasurfaces
Liming Liu, Yair Zarate, Haroldo T. Hattori
A full (2) phase modulation is critical for efficient wavefront manipulation. In this article, a metasurface based on graphene long/short-strip resonators is used to implement a…
Extraordinary transmission of nanohole lattices in gold films
Alexander Minovich, Haroldo T. Hattori, Ian McKerracher +4
We study experimentally the transmission of light through a square lattice of nanoholes perforated in a optically-thick gold film. We observe that the periodicity of the structure…
