A random laser based on diamond nanoneedles
Ngoc My Hanh Duong, Blake Regan, Milos Toth +2
Random lasers use radiative gain and multiple scatterers in disordered media to generate light amplification. In this study, we demonstrate a random laser based on diamond nanoneed…
Photocurrent Enhancement of Graphene Photodetectors by Photon Tunneling of Light into Surface Plasmons
Alireza Maleki, Benjamin P. Cumming, Min Gu +3
We demonstrate that surface plasmon resonances excited by photon tunneling through an adjacent dielectric medium enhance photocurrent detected by a graphene photodetector. The devi…
Digital Waveguide Adiabatic Passage Part 2: Experiment
Vincent Ng, Jesse A. Vaitkus, Zachary J. Chaboyer +5
Using a femtosecond laser writing technique, we fabricate and characterise three-waveguide digital adiabatic passage devices, with the central waveguide digitised into five discret…
Curved Gratings as Plasmonic Lenses for Linearly Polarised Light
Alireza Maleki, Thanh Phong Vo, Antoine Hautin +3
The ability of curved gratings as sectors of concentric circular gratings to couple linearly polarized light into focused surface plasmons is investigated by theory, simulation and…
