Search for high-mass exclusive diphoton production with tagged protons in proton-proton collisions at √s=13 TeV

Matthias Finger, Qian Wang, Varun Sharma, Konstantin Androsov, Jan Steggemann, Ian Smith, Xin Chen, Rakesh Chawla, Michele De Palma, Matteo Galli

A search is presented for high-mass exclusive diphoton production via photon-photon fusion in proton-proton collisions at root s = 13 TeV in events where both protons survive the interaction. The analysis utilizes data corresponding to an integrated lumino ...

Measurement of the inclusive and differential t(t)over-bar gamma cross sections in the dilepton channel and effective field theory interpretation in proton-proton collisions at root s=13 TeV

Matthias Finger, Varun Sharma, Olivier Martin, Ian Smith, Jean-François Carlin, Arvind Shah, Rakesh Chawla, Thomas Mountford, Chao Wang, João Miguel das Neves Duarte

The production cross section of a top quark pair in association with a photon is measured in proton-proton collisions in the decay channel with two oppositely charged leptons (e(+/-)mu(-/+), e(+)e(-), or mu(+)mu(-)). The measurement is performed using 138 ...

Are Photonic Nanojets Achromatic?

Toralf Scharf, Myun Sik Kim, Michail Symeonidis

In this work we study the evolution of the photonic nanojet (PNJ) phenomenon as the ratio of the sphere's diameter over the illumination wavelength changes, for microspheres with diameters from 2 mu m to 100 mu m. We measure the focal point position by usi ...

Diffractive Optical Elements Investigation in the Phase Domain

Toralf Scharf, Myun Sik Kim, Dong Cheon Kim, Michail Symeonidis

In this work we demonstrate the advantages of investigating diffractive optical elements in the phase domain. In this regime we can detect features that are not restrained by the diffraction limit and relate them to the geometrical and optical properties o ...

Inverse photonic design of functional elements that focus Bloch surface waves

Hans Peter Herzig, Myun Sik Kim, Babak Vosoughi Lahijani, Andreas Vetter

Bloch surface waves (BSWs) are sustained at the interface of a suitably designed one-dimensional (1D) dielectric photonic crystal and an ambient material. The elements that control the propagation of BSWs are defined by a spatially structured device layer ...

Bloch Surface Waves Using Graphene Layers: An Approach toward In-Plane Photodetectors

Hans Peter Herzig, Richa Dubey, Myun Sik Kim, Babak Vosoughi Lahijani

A dielectric multilayer platform was investigated as a foundation for two-dimensional optics. In this paper, we present, to the best of our knowledge, the first experimental demonstration of absorption of Bloch surface waves in the presence of graphene lay ...

Hybrid surface wave device

Hans Peter Herzig, Myun Sik Kim

We present a hybrid surface wave device, which combines Bloch surface wave (BSW) and plasmonic nanoantennas. BSWs offer in-plane dark-field illumination. Nanoantennas squeeze the incidence into nano-size and enable far-field readout without near-field tech ...

Stepwise Luneburg Lens for Bloch Surface Waves

Myun Sik Kim, Babak Vosoughi Lahijani

In order to enlarge the capability for in-plane manipulation of the Bloch surface wave (BSW), we investigate 2D gradient index (GRIN) optical components using a finite-difference time-domain (FDTD) numerical method. To ease difficulties in fabrication to a ...

Manipulation of Bloch surface waves: from subwavelength focusing to nondiffracting beam

Hans Peter Herzig, Myun Sik Kim

We present a different type of electromagnetic surface wave than a surface plasmon polariton (SPP), called Bloch surface wave (BSW). BSWs are sustained by dielectric multilayers, and therefore they do not suffer from dissipation. Their propagation length i ...

Magnetic spin-orbit interaction of light steers Bloch surface waves

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal, Hongying Zhang, Huihui Lü

We show the directional excitation of Bloch surface waves controlled by the magnetic field of light. The phenomenon in play is the first magnetic spin-orbit interaction of light. It opens new degrees of freedom in the manipulation of light and offers appea ...
