Polarization memory effect in a multimode fiber
Gauri Arora, Lyubov V. Amitonova
Optical memory effects are well-known types of amplitude-domain wave correlation enabling control over light scattered through diffusive materials or multimode fibers. In this lett…
Speckle-based 3D sub-diffraction imaging through a multimode fiber
Zhouping Lyu, Shih-Te Hung, Carlas S. Smith +1
A flexible multimode fiber is an exceptionally efficient tool for in vivo deep tissue imaging. Recent advances in compressive multimode fiber sensing allow for imaging with sub-dif…
Wavefront shaping and imaging through a multimode hollow-core fiber
Zhouping Lyu, Lyubov Amitonova
Multimode fibers recently emerged as compact minimally-invasive probes for high-resolution deep-tissue imaging. However, the commonly used silica fibers have a relatively low numer…
Quantitative phase imaging via a multimode fiber
Aleksandra Ivanina, Maxim Marshall, Ksenia Abrashitova +2
Label-free quantitative phase imaging is a vital tool for optical microscopy and metrology applications. A hair-thin multimode fiber stands out as a very attractive platform for mi…
Generative adversarial network for super-resolution imaging through a fiber
Wei Li, Ksenia Abrashitova, Gerwin Osnabrugge +1
A multimode fiber represents the ultimate limit in miniaturization of imaging endoscopes. Here we propose a fiber imaging approach employing compressive sensing with a data-driven…
Comparison of round- and square-core fibers for sensing, imaging and spectroscopy
Matthias C. Velsink, Zhouping Lyu, Pepijn W. H. Pinkse +1
Multimode fibers (MMFs) show great promise as miniature probes for sensing, imaging and spectroscopy applications. Different parameters of the fibers, such as numerical aperture, r…
Spatiotemporal focusing through a multimode fiber via time-domain wavefront shaping
Matthias C. Velsink, Lyubov V. Amitonova, Pepijn W. H. Pinkse
We shape fs optical pulses and deliver them in a single spatial mode to the input of a multimode fiber. The pulse is shaped in time such that at the output of the multimode fiber a…
Endo-microscopy beyond the Abbe and Nyquist limits
Lyubov V. Amitonova, Johannes F. de Boer
For several centuries, far-field optical microscopy has remained a key instrument in many scientific disciplines including physical, chemical and biomedical research. Nonetheless,…
Blind focusing through strongly scattering media using wavefront shaping with nonlinear feedback
Gerwin Osnabrugge, Lyubov V. Amitonova, Ivo M. Vellekoop
Scattering prevents light from being focused in turbid media. The effect of scattering can be negated through wavefront shaping techniques when a localized form of feedback is avai…
Deep-tissue large field of view imaging by Fourier conjugate adaptive optics
Lyubov V. Amitonova
Light microscopy enables multifunctional imaging of biological specimens at unprecedented depths and resolutions. However, the performance of all optical methods degrades with the…
Quantum key establishment via a multimode fiber
Lyubov V. Amitonova, Tristan B. H. Tentrup, Ivo M. Vellekoop +1
Quantum communication aims to provide absolutely secure transmission of secret information. State-of-the-art methods encode symbols into single photons or coherent light with much…
Aberrations of the point spread function of a multimode fiber
Adrien Descloux, Lyubov V. Amitonova, Pepijn W. H. Pinkse
We investigate the point spread function of a multimode fiber. The distortion of the focal spot created on the fiber output facet is studied for a variety of the parameters. We dev…
The rotational memory effect of a multimode fiber
L. V. Amitonova, A. P. Mosk, P. W. H. Pinkse
We demonstrate the rotational memory effect in a multimode fiber. Rotating the incident wavefront around the fiber core axis leads to a rotation of the resulting pattern of the fib…
