Photon statistics of incoherent cathodoluminescence with continuous and pulsed electron beams
Magdalena Solà-Garcia, Kelly W. Mauser, Matthias Liebtrau +3
Photon bunching in incoherent cathodoluminescence (CL) spectroscopy originates from the fact that a single high-energy electron can generate multiple photons when interacting with…
Towards fully integrated photonic displacement sensors
Ankan Bag, Martin Neugebauer, Uwe Mick +3
The field of optical metrology with its high precision position, rotation and wavefront sensors represents the basis for lithography and high resolution microscopy. However, the on…
Towards Polarization-based Excitation Tailoring for Extended Raman Spectroscopy
Simon Grosche, Richard Hünermann, George Sarau +4
Undoubtedly, Raman spectroscopy is one of the most elaborated spectroscopy tools in materials science, chemistry, medicine and optics. However, when it comes to the analysis of nan…
Chiroptical response of a single plasmonic nanohelix
Paweł Woźniak, Israel De Leon, Katja Höflich +4
We investigate the chiroptical response of a single plasmonic nanohelix interacting with a weakly-focused circularly-polarized Gaussian beam. The optical scattering at the fundamen…
Mode-matching for Optical Antennas
Thorsten Feichtner, Silke Christiansen, Bert Hecht
The emission rate of a point dipole can be strongly increased in presence of a well-designed optical antenna. Yet, optical antenna design is largely based on radio-frequency rules,…
Strong plasmonic enhancement of biexciton emission: controlled coupling of a single quantum dot to a gold nanocone antenna
Korenobu Matsuzaki, Simon Vassant, Hsuan-Wei Liu +8
Multiexcitonic transitions and emission of several photons per excitation comprise a very attractive feature of semiconductor quantum dots for optoelectronics applications. However…
Plasmonic Gold Helices for the visible range fabricated by oxygen plasma purification of electron beam induced deposits
Caspar Haverkamp, Katja Höflich, Sara Jäckle +2
Electron beam induced deposition (EBID) currently provides the only direct writing technique for truly three-dimensional nanostructures with geometrical features below 50 nm. Unfor…
Photonic light trapping in silicon nanowire arrays: deriving and overcoming the physical limitations
Sebastian W. Schmitt, Silke H. Christiansen
Hexagonally aligned, free-standing silicon nanowire (SiNW) arrays serve as photonic resonators which, as compared to a silicon (Si) thin film, do not only absorb more visible (VIS)…
Electromechanically Tunable Suspended Optical Nano-antenna
Kai Chen, Gary Razinskas, Thorsten Feichtner +3
Coupling mechanical degrees of freedom with plasmonic resonances has potential applications in optomechanics, sensing, and active plasmonics. Here we demonstrate a suspended two-wi…
Unveiling the optical properties of a metamaterial synthesized by electron-beam-induced deposition
Paweł Woźniak, Katja Höflich, Gerald Brönstrup +3
The direct writing using a focused electron beam allows for fabricating truly three-dimensional structures of sub-wavelength dimensions in the visible spectral regime. The resultin…
Direct laser planting of hybrid Au-Ag/C nanostructures - nanoparticles, flakes and flowers
Alina Manshina, Anastasia Povolotckaia, Muhammad Bashouti +6
We demonstrate a new approach for forming hybrid metal/carbonaceous nanostructures in a controlled direct laser planting process. Au-Ag nanoclusters in amorphous or crystalline car…
Observation of strongly enhanced photoluminescence from inverted cone-shaped silicon nanostuctures
Sebastian W. Schmitt, George Sarau, Silke H. Christiansen
Silicon nanowires (SiNWs) attached to a wafer substrate are converted to inversely tapered silicon nanocones (SiNCs). After excitation with visible light, individual SiNCs show a 2…
Interfacing transitions of different alkali atoms and telecom bands using one narrowband photon pair source
Gerhard Schunk, Ulrich Vogl, Dmitry V. Strekalov +7
Quantum information technology strongly relies on coupling of optical photons with narrowband quantum systems, such as quantum dots, color centers, and atomic systems. This couplin…
A Sub--Volume Cantilever-based Fabry-Pérot Cavity
Hrishikesh Kelkar, Daqing Wang, Diego Martín-Cano +4
We report on the realization of an open plane-concave Fabry-Pérot resonator with a mode volume below at optical frequencies. We discuss some of the less common features of th…
Fracture strength and Young's modulus of ZnO nanowires
S. Hoffmann, F. Ostlund, J. Michler +4
The fracture strength of ZnO nanowires vertically grown on sapphire substrates was measured in tensile and bending experiments. Nanowires with diameters between 60 and 310 nm and a…
