Coherent control of an optical tweezer phonon laser
Kai Zhang, Kewen Xiao, Danika Luntz-Martin +4
The creation and manipulation of coherence continues to capture the attention of scientists and engineers. The optical laser is a canonical example of a system that, in principle,…
All-dielectric hybrid VIS-NIR dual-function metasurface
Pei Xiong, Daniel K. Nikolov, Fei Cheng +2
Metasurfaces are a promising technology that can serve as a compact alternative to conventional optics while providing multiple functions depending on the properties of the inciden…
Experimental realization of supergrowing fields
Sethuraj K. R., Tathagata Karmakar, S. A. Wadood +2
Supergrowth refers to the local amplitude growth rate of a signal being faster than its fastest Fourier mode. In contrast, superoscillation pertains to the variation of the phase.…
Supergrowth and sub-wavelength object imaging
Tathagata Karmakar, Abhishek Chakraborty, A. Nick Vamivakas +1
We further develop the concept of supergrowth [Jordan, Quantum Stud.: Math. Found. , 285-292 (2020)], a phenomenon complementary to superoscillation, defined as the loc…
Coherence effects on estimating general sub-Rayleigh object distribution moments
Kevin Liang, S. A. Wadood, A. N. Vamivakas
Quantum Fisher information and signal-to-noise ratio bounds are derived for the estimation of moments of general partially coherent objects. Under an asymptotic analysis in the sub…
Experimental demonstration of superresolution of partially coherent light sources using parity sorting
S. A. Wadood, Kevin Liang, Yiyu Zhou +8
Analyses based on quantum metrology have shown that the ability to localize the positions of two incoherent point sources can be significantly enhanced through the use of mode sort…
Confocal super-resolution microscopy based on a spatial mode sorter
Katherine K. M. Bearne, Yiyu Zhou, Boris Braverman +6
Spatial resolution is one of the most important specifications of an imaging system. Recent results in quantum parameter estimation theory reveal that an arbitrarily small distance…
Injection locking of a levitated optomechanical oscillator for precision force sensing
Siamak Dadras, Robert M. Pettit, Danika R. Luntz-Martin +3
We report on the injection locking of an optically levitated nanomechanical oscillator (a silica nanosphere) to resonant intensity modulations of an external optical signal. We exp…
Modal Majorana sphere and hidden symmetries of structured-Gaussian beams
R. Gutiérrez-Cuevas, S. A. Wadood, A. N. Vamivakas +1
Structured-Gaussian beams are shown to be fully and uniquely represented by a collection of points (or constellation) on the surface of the modal Majorana sphere, providing a compl…
Quantum-limited estimation of the axial separation of two incoherent point sources
Yiyu Zhou, Jing Yang, Jeremy D. Hassett +6
Improving axial resolution is crucial for three-dimensional optical imaging systems. Here we present a scheme of axial superresolution for two incoherent point sources based on spa…
Measuring geometric phase without interferometry
T. Malhotra, R. Gutiérrez-Cuevas, J. Hassett +3
A simple non-interferometric approach for probing the geometric phase of a structured Gaussian beam is proposed. Both the Gouy and Pancharatnam-Berry phases can be determined from…
Polarization Coherence Theorem
J. H. Eberly, X. -F. Qian, A. N. Vamivakas
Visibility and distinguishability quantify wave-ray duality: . We join them to polarization via the Polarization Coherence Theorem, a tight equality: $…
Emerging Connections: Quantum and Classical Optics
Xiao-Feng Qian, A. Nick Vamivakas, Joseph H. Eberly
Quantum optics and classical optics have coexisted for nearly a century as two distinct, self-consistent descriptions of light. What influences there were between the two domains a…
Basis-neutral Hilbert-space analyzers
Lane Martin, Davood Mardani, H. Esat Kondakci +7
Interferometry is one of the central organizing principles of optics. Key to interferometry is the concept of optical delay, which facilitates spectral analysis in terms of time-ha…
