Geometric phase and wave-particle duality of the photon
Elvis Pillinen, Atri Halder, Ari T. Friberg +2
The concepts of geometric phase and wave-particle duality are interlinked to several fundamental phenomena in quantum physics, but their mutual relationship still forms an uncharte…
Cross-spectral purity of the Stokes parameters in random nonstationary electromagnetic beams
Jyrki Laatikainen, Ari T. Friberg, Tero Setälä
We consider cross-spectral purity in random nonstationary electromagnetic beams in terms of the Stokes parameters representing the spectral density and the spectral polarization st…
Finite size mediated radiative coupling of lasing plasmonic bound state in continuum
Benjamin O. Asamoah, Marek Nečada, Wenzhe Liu +12
Radiative properties of lasing plasmonic bound state in continuum are analyzed. The topological charge of the lasing signal is analyzed in the far field as well as in the source pl…
Inverse design of focused vector beams for mode excitation in optical nanoantennas
Xiaorun Zang, Ari T. Friberg, Tero Setälä +1
We propose a free-space, inverse design of nanostructure's effective mode-matching fields via a backward propagation of tightly focused vector beams to the pupil plane of an aplana…
Metamaterials designed for enhanced ENZ properties]{Metamaterials designed for enhanced ENZ properties
Matias Koivurova, Tommi Hakala, Jari Turunen +3
We examine layered metamaterial structures consisting of alternating films of epsilon-near-zero (ENZ) and dielectric material, and show that for such a stack it is possible to enha…
Ghost optical coherence tomography
Caroline Amiot, Piotr Ryczkowski, Ari T. Friberg +2
We demonstrate experimentally ghost optical coherence tomography using a broadband incoherent supercontinuum light source with shot-to-shot random spectral fluctuations. The techni…
Broadband continuous spectral ghost imaging for high resolution spectroscopy
Caroline Amiot, Piotr Ryczkowski, Ari. T. Friberg +2
Ghost imaging is an unconventional imaging technique that generates high resolution images by correlating the intensity of two light beams, neither of which independently contains…
Magnified Time-Domain Ghost Imaging
Piotr Ryczkowski, Margaux Barbier, Ari T. Friberg +2
Ghost imaging allows to image an object without directly seeing this object. Origi- nally demonstrated in the spatial domain using classical or entangled-photon sources, it was rec…
Phase Noise Influence in Optical OFDM Systems employing RF Pilot Tone for Phase Noise Cancellation
Gunnar Jacobsen, Leonid G. Kazovsky, Tianhua Xu +4
For coherent and direct-detection Orthogonal Frequency Division Multiplexed (OFDM) systems employing radio frequency (RF) pilot tone phase noise cancellation the influence of laser…
