Revising quantum optical phenomena in adatoms coupled to graphene nanoantennas

June 8, 2022
Author(s)
Garnett W. Bryant, Miriam Kosik, Marvin Muller, Karolina Slowik, Andres Ayuela, Carsten Rockstuhl, Marta Pelc
Graphene flakes acting as photonic nanoantennas sustain strong electromagnetic field localization and enhancement. To exploit the field enhancement, quantum emitters such as atoms or molecules should be positioned in such close proximity to the flake that

High throughput nanoimaging of thermal conductivity and interfacial thermal conductance

May 17, 2022
Author(s)
Mingkang Wang, Georg Ramer, Diego Perez, Georges Pavlidis, Jeffrey Schwartz, Liya Yu, Robert Ilic, Vladimir Aksyuk, Andrea Centrone
Thermal properties of materials are often determined by measuring thermalization processes. Measuring such properties at the nanoscale, however, requires high sensitivity, high temporal, and high spatial resolutions concurrently, which is beyond the

Exceptional points in lossy media lead to deep polynomial wave penetration with spatially uniform power loss

April 21, 2022
Author(s)
Alexander Yulaev, Sangsik Kim, Qing Li, Daron Westly, Brian Roxworthy, Kartik Srinivasan, Vladimir Aksyuk
Waves entering a spatially uniform lossy medium typically undergo exponential decay, arising from either the energy loss of the Beer–Lambert–Bouguer transmission law or the evanescent penetration during reflection. Recently, exceptional point singularities

Thermal release tape-assisted semiconductor membrane transfer process for hybrid photonic devices embedding quantum emitters

April 19, 2022
Author(s)
Cori Haws, Biswarup Guha, Edgar Perez, Marcelo Davanco, Jin Dong Song, Kartik Srinivasan, Luca Sapienza
Being able to combine different materials allows taking advantage of different properties and device engineering that cannot be found or exploited within a single system. In the realm of quantum and nanophotonics, for instance, one might want to increase

Laser-lithographically written micron-wide superconducting nanowire single-photon detectors

March 23, 2022
Author(s)
Maximilian Protte, Varun Verma, Jan Philipp Hopker, Richard Mirin, Sae Woo Nam, Tim Bartley
In this paper, we demonstrate our results on micron-wide tungsten silicide superconducting nanowire single-photon detectors fabricated by laser lithography. Laser-lithographically written devices allow for fast and easy structuring of large areas while

Strong coupling between a topological insulator and a III-V heterostructure at terahertz frequency

March 8, 2022
Author(s)
Garnett W. Bryant, D. Quang To, Zhengtianye Wang, Q. Dai Ho, Ruiqi Hu, Wilder Acuna, Yongchen Liu, Anderson Janotti, Joshua Zide, Stephanie Law, Matthew Doty
We probe theoretically the emergence of strong coupling in a system consisting of a topological insulator (TI) and a III-V heterostructure using a numerical approach based on the scattering matrix formalism. Speci cally, we investigate the interactions

Full-Stokes polarimetry for visible light enabled by an all-dielectric metasurface

February 20, 2022
Author(s)
Yongze Ren, Shihao Guo, Wenqi Zhu, Pengcheng Huo, Sijia Liu, Song Zhang, Peng Chen, Lu Chen, Henri Lezec, Amit Agrawal, Yanqing Lu, Ting Xu
Decoding arbitrary polarization information from an optical field has triggered unprecedented endeavors in polarization imaging, remote sensing and information processing. Therefore, developing a polarization detection device with full on-chip integration

Dependence of Single-Wall Carbon Nanotubes Alignment on the Filter Membrane Interface in Slow Vacuum Filtration

January 22, 2022
Author(s)
Jeffrey Fagan, Angela R. Hight Walker, Adam Biacchi, Andrei Kolmakov, Zia Macdermid, William D. Rice, Joshua Walker, Thomas Searles
The recent development of slow vacuum filtration (SVF) technology has shown great promise for reproducibly producing high-quality, large-area aligned films of single-wall carbon nanotubes (SWCNTs) from solution-based nanotube dispersions. In contrast to

Charge Density Wave Activated Excitons in MoSe2

January 5, 2022
Author(s)
Jaydeep Joshi, Benedikt Scharf, Igor Mazin, Sergiy Krylyuk, Daniel Campbell, Albert Davydov, Johnpierre Paglione, Igor Zutic, Patrick Vora
Layered materials enable the assembly of a new class of heterostructures where lattice-matching is no longer a requirement. Interfaces in these heterostructures therefore become a fertile ground for new physics as dissimilar phenomena can be coupled via

Ultra-broadband Kerr microcomb through soliton spectral translation

December 14, 2021
Author(s)
Gregory Moille, Edgar Perez, Jordan Stone, Ashutosh Rao, Xiyuan Lu, Tahmid Rahman, Yanne Chembo, Kartik Srinivasan
Broad bandwidth and stable microresonator frequency combs are critical for optical atomic clocks, optical frequency synthesis, dual comb spectroscopy, and a host of other applications that require accurate and precise optical frequency measurements in a

Modification of the optical properties of molecular chains upon coupling to adatoms

December 13, 2021
Author(s)
Garnett W. Bryant, Marvin Muller, Miriam Kosik, Marta Pelc, Karolina Slowik, Andres Ayuela, Carsten Rockstuhl
Adsorbed atoms (adatoms) coupled to the matrix of solid state host materials as impurities can signi cantly modify their properties. Especially in low-dimensional materials, such as one-dimensional organic polymer chains or quasi-one-dimensional graphene

A simple imaging solution for chip-scale laser cooling

November 1, 2021
Author(s)
John Kitching, Gabriela Martinez, A, Gregazzi, Paul Griffin, Aidan Arnold, D. P. Burt, Rodolphe Bouldot, Erling Riis, James McGilligan
We demonstrate a simple stacked scheme that enables absorption imaging through a hole in the surface of a grating magneto-optical trap (GMOT) chip, placed immediately below a micro-fabricated vacuum cell. The imaging scheme is capable of overcoming the

Generation of perfect vortex beams by dielectric geometric metasurface for visible light

October 31, 2021
Author(s)
Qianwei Zhou, Mingze Liu, Wenqi Zhu, Lu Chen, Yongze Ren, Henri Lezec, Yanqing Lu, Ting Xu, Amit Agrawal
Perfect vortex beam (PVB) is a propagating optical field carrying orbital angular momentum (OAM) with a radial intensity profile that is independent of topological charge. PVB can be generated through the Fourier transform of a Bessel-Gaussian beam, which
