Plasmonic antenna coupling to hyperbolic phonon-polaritons for sensitive and fast mid-infrared photodetection with graphene
Sebastián Castilla, Ioannis Vangelidis, Varun-Varma Pusapati +13
Integrating and manipulating the nano-optoelectronic properties of Van der Waals heterostructures can enable unprecedented platforms for photodetection and sensing. The main challe…
Fast and Sensitive Terahertz Detection Using an Antenna-Integrated Graphene pn Junction
Sebastián Castilla, Bernat Terrés, Marta Autore +11
Although the detection of light at terahertz (THz) frequencies is important for a large range of applications, current detectors typically have several disadvantages in terms of se…
Hot electrons modulation of third harmonic generation in graphene
G. Soavi, G. Wang, H. Rostami +8
Hot electrons dominate the ultrafast (fs-ps) optical and electronic properties of metals and semiconductors and they are exploited in a variety of applications including phot…
Surface-Enhanced Raman Spectroscopy of Graphene Integrated in Plasmonic Silicon Platforms with Three-Dimensional Nanotopography
Maria Kanidi, Alva Dagkli, Nikolaos Kelaidis +8
Integrating graphene with plasmonic nanostructures results in multifunctional hybrid systems with enhanced performance for numerous applications. In this work, we take advantage of…
Deep and fast free-space electro-absorption modulation in a mobility-independent graphene-loaded Bragg resonator
Spyros Doukas, Alma Chatzilari, Alva Dagkli +2
Deep and fast electro-optic modulation is critical for high-speed near infrared signal processing. We combine the electro-absorption tunability of graphene with the high-Q resonanc…
Flat-band localization and self-collimation of light in photonic crystals
Nojoon Myoung, Hee Chul Park, Ajith Ramachandran +2
We investigate the optical properties of a photonic crystal composed of a quasi-one-dimensional flat-band lattice array through finite-difference time-domain simulations. The photo…
