Journal ArticleDOI
High-Q MgF₂ whispering gallery mode resonators for refractometric sensing in aqueous environment.
TL;DR: Experimental data showing the interferometrically measured evanescent field decay and the sensitivity of mm-sized MgF₂ whispering gallery mode resonators immersed in water show reasonable agreement with the developed theory.
Journal ArticleDOI
Three-photon head-mounted microscope for imaging deep cortical layers in freely moving rats
Alexandr Klioutchnikov,Damian J. Wallace,Michael H. Frosz,Richard Zeltner,Juergen Sawinski,Verena Pawlak,Kay-Michael Voit,Philip St. J. Russell,Jason N. D. Kerr +8 more
TL;DR: A head-mounted three-photon microscope based on a custom-designed optical fiber and dispersion compensation enables imaging of activity from neuronal populations deep in the cortex of freely moving rats.
Journal ArticleDOI
High-Q MgF$_2$ whispering gallery mode resonators for refractometric sensing in aqueous environment
TL;DR: In this paper, the authors present experiments on refractometric sensing with ultrahigh-Q, crystalline, birefringent magnesium fluoride (MgF$_2$) whispering gallery mode resonators.
Journal ArticleDOI
Long-range optical trapping and binding of microparticles in hollow-core photonic crystal fibre.
Dmitry S. Bykov,Shangran Xie,Richard Zeltner,Richard Zeltner,Andrey Machnev,Gordon K. L. Wong,Tijmen G. Euser,Tijmen G. Euser,Philip St. J. Russell,Philip St. J. Russell +9 more
TL;DR: Bykov et al. as mentioned in this paper reported the observation of long-range optical binding of multiple levitated microparticles mediated by intermodal scattering and interference inside the evacuated core of a hollow-core photonic crystal fiber (HC-PCF).
Journal ArticleDOI
Polarization-Selective Out-Coupling of Whispering-Gallery Modes
Florian Sedlmeir,Florian Sedlmeir,Matthew R. Foreman,Matthew R. Foreman,Ulrich Vogl,Ulrich Vogl,Richard Zeltner,Richard Zeltner,Gerhard Schunk,Gerhard Schunk,Dmitry Strekalov,Dmitry Strekalov,Christoph Marquardt,Christoph Marquardt,Gerd Leuchs,Gerd Leuchs,Harald G. L. Schwefel +16 more
TL;DR: In this article, the authors demonstrate a scheme, exploiting birefringence in either the coupling prism or the resonator, which can be used to tune the coupling strength to pump and signal modes.
