Journal ArticleDOI
A Metalens with a Near-Unity Numerical Aperture
Ramón Paniagua-Domínguez,Ye Feng Yu,Egor Khaidarov,Egor Khaidarov,Sumin Choi,Victor Leong,Reuben M. Bakker,Xinan Liang,Yuan Hsing Fu,Vytautas Valuckas,Leonid A. Krivitsky,Arseniy I. Kuznetsov +11 more
TL;DR: This work, based on diffractive elements that can efficiently bend light at angles as large as 82°, represents a step beyond traditional optical elements and existing flat optics, circumventing the efficiency drop associated with the standard, phase mapping approach.
Journal ArticleDOI
Generalized Brewster effect in dielectric metasurfaces
Ramón Paniagua-Domínguez,Ye Feng Yu,Andrey E. Miroshnichenko,Leonid A. Krivitsky,Yuan Hsing Fu,Vytautas Valuckas,Vytautas Valuckas,Leonard Gonzaga,Yeow Teck Toh,Anthony Yew Seng Kay,Boris Luk'yanchuk,Arseniy I. Kuznetsov +11 more
TL;DR: It is theoretically predicted that a properly designed all-dielectric metasurface exhibits a generalized Brewster's effect potentially for any angle, wavelength and polarization of choice, and experimentally demonstrated for an array of silicon nanodisks at visible wavelengths.
Journal ArticleDOI
Infrared spectroscopy with visible light
TL;DR: In this article, the authors developed a technique that allows spectral measurements in the infrared range using visible-spectral-range components, based on nonlinear interference of infrared and visible photons, produced via spontaneous parametric down conversion.
Journal ArticleDOI
Continuous Wave Second Harmonic Generation Enabled by Quasi-Bound-States in the Continuum on Gallium Phosphide Metasurfaces
Aravind P. Anthur,Haizhong Zhang,Ramón Paniagua-Domínguez,Dmitry A. Kalashnikov,Son Tung Ha,Tobias W. W. Maß,Arseniy I. Kuznetsov,Leonid A. Krivitsky +7 more
TL;DR: In this article, the authors demonstrate visible range, continuous wave (CW) SHG by combining the attractive material properties of gallium phosphide with high quality-factor photonic modes enabled by bound states in the continuum.

TL;DR: In this paper, the authors focus on using quantum light as a powerful sensing and spectroscopic tool to reveal novel information about complex molecules that is not accessible by classical light, and they aim at bridging the quantum optics and the spectroscopy communities which normally have opposite goals: manipulating complex light states with simple matter.
