Mass and charge transport in micro and nano-fluidic channels
N. A. Mortensen, L. H. Olesen, F. Okkels +1
We consider laminar flow of incompressible electrolytes in long, straight channels driven by pressure and electro-osmosis. We use a Hilbert space eigenfunction expansion to address…
Highly dispersive photonic band-gap-edge optofluidic biosensors
Sanshui Xiao, Niels Asger Mortensen
Highly dispersive photonic band-gap-edge optofluidic biosensors are studied theoretically. We demonstrate that these structures are strongly sensitive to the refractive index of th…
Mesoscopic magnetism in dielectric photonic crystal meta materials: topology and inhomogeneous broadening
Niels Asger Mortensen, Sanshui Xiao, Didier Felbacq
We consider meta materials made from a two-dimensional dielectric rod-type photonic crystal. The magnetic response is studied within the recently developed homogenization theory an…
Photonic crystal fibres: mapping Maxwell's equations onto a Schrodinger equation eigenvalue problem
Niels Asger Mortensen
We consider photonic crystal fibres (PCFs) made from arbitrary base materials and introduce a short-wavelength approximation which allows for a mapping of the Maxwell's equations o…
Nonlinear photonic crystal fibres: pushing the zero-dispersion toward the visible
Kunimasa Saitoh, Masanori Koshiba, Niels Asger Mortensen
The strong waveguide dispersion in photonic crystal fibres provides unique opportunities for nonlinear optics with a zero-dispersion wavelength far below the limit of ~1.3 mi…
Calculation of optical-waveguide grating characteristics using Green's functions and the Dyson's equation
Lars Rindorf, Niels Asger Mortensen
We present a method for calculating the transmission spectra, dispersion, and time delay characteristics of optical-waveguide gratings based on Green's functions and Dyson's equati…
Frequency response in surface-potential driven electro-hydrodynamics
L. Ejsing, K. Smistrup, C. M. Pedersen +2
Using a Fourier approach we offer a general solution to calculations of slip velocity within the circuit description of the electro-hydrodynamics in a binary electrolyte confined b…
