Journal ArticleDOI
Helical-wavefront laser beams produced with a spiral phaseplate
TL;DR: In this paper, a spiral phaseplate can convert a TEM00 laser beam into a helical wavefront beam with a phase singularity at its axis, and the diffractive-optical effect of the spiral phase plate is implemented by index matching a macroscopic structure in an optical immersion.
Journal ArticleDOI
Strained silicon as a new electro-optic material
Rune Shim Jacobsen,Karin Nordström Andersen,Karin Nordström Andersen,Peter Ingo Borel,Jacob Fage-Pedersen,Lars Hagedorn Frandsen,Ole Hansen,Martin Kristensen,Martin Kristensen,Andrei V. Lavrinenko,Gaid Moulin,Haiyan Ou,Christophe Peucheret,Beata Zsigri,Anders Bjarklev +14 more
TL;DR: The strain-induced linear electro-optic effect may be used to remove a bottleneck in modern computers by replacing the electronic bus with a much faster optical alternative.
Journal ArticleDOI
Photonic-crystal waveguide biosensor
N. Skivesen,Amélie Têtu,Martin Kristensen,Jørgen Kjems,Lars Hagedorn Frandsen,Peter Ingo Borel +5 more
TL;DR: A broad, dynamic refractive index sensing range extending from air to high viscous fluids is presented, and a photonic-crystal waveguide sensor is presented for biosensing.
Journal ArticleDOI
Topology optimization and fabrication of photonic crystal structures.
Peter Ingo Borel,Anders Harpøth,Lars Hagedorn Frandsen,Martin Kristensen,P. Shi,Jakob Søndergaard Jensen,Ole Sigmund +6 more
TL;DR: Exceptional transmission through a photonic crystal waveguide Z-bend is obtained using this inverse design strategy and a large low loss bandwidth of more than 200 nm for the bandgap polarization is experimentally confirmed.
Journal ArticleDOI
Comprehensive FDTD modelling of photonic crystal waveguide components
Andrei V. Lavrinenko,Peter Ingo Borel,Lars Hagedorn Frandsen,Morten Thorhauge,Anders Harpøth,Martin Kristensen,Tapio Niemi,Harold M. H. Chong +7 more
TL;DR: Comprehensive numerical calculations have been performed and it is found that within the experimental fabrication tolerances the calculations correctly predict the measured transmission levels and other major transmission features.
