Ultrabroadband Coherent Perfect Absorption with Composite Graphene Metasurfaces
Wei Zou, Tianjing Guo, Christos Argyropoulos
We investigate the design and performance of a new multilayer graphene metasurface for achieving ultrabroadband coherent perfect absorption (CPA) in the THz regime. The proposed st…
Enhanced nonlinear optical effects in drift-biased nonreciprocal graphene plasmonics
S. Ali Hassani Gangaraj, Boyuan Jin, Christos Argyropoulos +1
Nonlinear light-matter interactions are typically enhanced by increasing the local field and its interaction time with matter. Conventional methods to achieve these goals are based…
Unraveling the formation dynamics of metallic femtosecond laser induced periodic surface structures
L. Khosravi Khorashad, A. Reicks, A. Erickson +6
Femtosecond laser surface processing (FLSP) is an emerging fabrication technique to efficiently control the surface morphology of many types of materials including metals. However,…
Hybrid Graphene-Plasmon Gratings
Tianjing Guo, Christos Argyropoulos
Graphene can support surface plasmons with higher confinement, lower propagation loss, and substantially more tunable response compared to usual metal-based plasmonic structures. I…
Plasmon Enhanced Quantum Properties of Single Photon Emitters with Hybrid Hexagonal Boron Nitride Silver Nanocube Systems
Mohammadjavad Dowran, Andrew Butler, Suvechhya Lamichhane +5
Hexagonal boron nitride (hBN) has emerged as a promising ultrathin host of single photon emitters (SPEs) with favorable quantum properties at room temperature, making it a highly d…
Exceptional points in parity-time symmetric plasmonic Huygens metasurfaces
Andrew Butler, Christos Argyropoulos
Parity-Time (PT) symmetric optical structures exhibit several unique and interesting characteristics with the most popular being exceptional points. While the emerging concept of P…
