Limits of slow-light in photonic crystals
Jesper Goor Pedersen, Sanshui Xiao, Niels Asger Mortensen
While ideal photonic crystals would support modes with a vanishing group velocity, state-of-the art structures have still only provided a slow-down by roughly two orders of magnitu…
Resonant-tunnelling-assisted crossing for subwavelength plasmonic slot waveguides
Sanshui Xiao, Niels Asger Mortensen
We theoretically investigate the properties of crossing for two perpendicular subwavelength plasmonic slot waveguides. We show that, when encountering nano intersection, the crosst…
Nanostructure design for surface-enhanced Raman spectroscopy - prospects and limits
Sanshui Xiao, Niels Asger Mortensen, Antti-Pekka Jauho
Surface-enhanced Raman spectroscopy (SERS) allows single-molecule detection due to the strong field localization occurring at sharp bends or kinks of the metal-vacuum interface. An…
Slow-light enhanced absorption for bio-chemical sensing applications: potential of low-contrast lossy materials
Jesper Pedersen, Sanshui Xiao, Niels Asger Mortensen
Slow-light enhanced absorption in liquid-infiltrated photonic crystals has recently been proposed as a route to compensate for the reduced optical path in typical lab-on-a-chip sys…
