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…
Optical properties of graphene antidot lattices
Thomas G. Pedersen, Christian Flindt, Jesper Pedersen +3
Undoped graphene is semi-metallic and thus not suitable for many electronic and optoelectronic applications requiring gapped semiconductor materials. However, a periodic array of h…
Graphene Antidot Lattices - Designed Defects and Spin Qubits
Thomas G. Pedersen, Christian Flindt, Jesper Pedersen +3
Antidot lattices, defined on a two-dimensional electron gas at a semiconductor heterostructure, are a well-studied class of man-made structures with intriguing physical properties.…
Electro-viscous effects in capillary filling of nanochannels
Niels Asger Mortensen, Anders Kristensen
We theoretically examine the widespread hypothesis of an electro-viscous origin of the increase in apparent viscosity observed in recent experiments on capillary filling of nanocha…
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…
Spin qubits in antidot lattices
Jesper Pedersen, Christian Flindt, Niels Asger Mortensen +1
We suggest and study designed defects in an otherwise periodic potential modulation of a two-dimensional electron gas as an alternative approach to electron spin based quantum info…
Designed defects in 2D antidot lattices for quantum information processing
Jesper Pedersen, Christian Flindt, Niels Asger Mortensen +1
We propose a new physical implementation of spin qubits for quantum information processing, namely defect states in antidot lattices defined in the two-dimensional electron gas at…
