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 plasmon polariton graphene photodetectors
T. J. Echtermeyer, S. Milana, U. Sassi +4
The combination of plasmonic nanoparticles and graphene enhances the responsivity and spectral selectivity of graphene-based photodetectors. However, the small area of the metal-gr…
Highly Sensitive Gas and Temperature Sensor Based on Conductance Modulation in Graphene with Multiple Magnetic Barriers
Nojoon Myoung, Elefterios Lidorikis
The electronic and transport properties of graphene modulated by magnetic barrier arrays are derived for finite temperature. Prominent conductance gaps, originating from quantum in…
Few-cycle pulses from a graphene mode-locked all-fiber laser
D. Purdie, D. Popa, V. J. Wittwer +6
We combine a graphene mode-locked oscillator with an external compressor and achieve~29fs pulses with~52mW average power. This is a simple, low-cost, and robust setup, entirely fib…
