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…
Experimental Demonstration of Spectral Intensity Optical Coherence Tomography
Piotr Ryczkowski, Jari Turunen, Ari T. Friberg +1
We demonstrate experimentally quantum-inspired, spectral-domain intensity optical coherence tomography. We show that the technique allows for both axial resolution improvement and…
Polarimetry by classical ghost diffraction
Henri Kellock, Tero Setälä, Ari T. Friberg +1
We present a technique for studying the polarimetric properties of a birefringent object by means of classical ghost diffraction. The standard ghost diffraction setup is modified t…
Image quality in double- and triple-intensity ghost imaging with classical partially polarized light
Henri Kellock, Tero Setälä, Tomohiro Shirai +1
Classical ghost imaging is a correlation-imaging technique in which the image of the object is found through intensity correlations of light. We analyze three different quality par…
