Plasmonic Nano-Gap Tilings: Light-Concentrating Surfaces for Low-Loss Photonic Integration
Paul M. Z. Davies, Joachim M. Hamm, Yannick Sonnefraud +2
Owing to their ability to concentrate light on nanometer scales, plasmonic surface structures are ideally suited for on-chip functionalization with nonlinear or gain materials. How…
Dispersive Media Subcell Averaging in the FDTD Method using Corrective Surface Currents
Joachim Hamm, Fabian Renn, Ortwin Hess
We present a corrective subcell averaging technique that improves on the accuracy of the volume-averaged finite-difference time-domain (FDTD) method in the presence of dispersive m…
Plasmonic Nanolasers Without Cavity, Threshold and Diffraction Limit using Stopped Light
Kosmas L. Tsakmakidis, Joachim M. Hamm, Tim W. Pickering +1
We present a plasmonic waveguide where light pulses are stopped at well-accessed complex-frequency zero-group-velocity points. Introducing gain at such points results in cavity-fre…
