Polarization Controlled Directional Scattering for Nanoscopic Position Sensing
Martin Neugebauer, Paweł Woźniak, Ankan Bag +2
Controlling the propagation and coupling of light to sub-wavelength antennas is a crucial prerequisite for many nanoscale optical devices. Recently, the main focus of attention has…
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…
Quantum Uncertainty in the Beam Width of Spatial Optical Modes
Vanessa Chille, Peter Banzer, Andrea Aiello +4
We theoretically investigate the quantum uncertainty in the beam width of transverse optical modes and, for this purpose, define a corresponding quantum operator. Single mode state…
Classically entangled optical beams for high-speed kinematic sensing
Stefan Berg-Johansen, Falk Töppel, Birgit Stiller +6
Tracking the kinematics of fast-moving objects is an important diagnostic tool for science and engineering. Existing optical methods include high-speed CCD/CMOS imaging, streak cam…
Transverse spin of light for all wavefields
Andrea Aiello, Peter Banzer
It has been known for a long time that light carries both linear and angular momenta parallel to the direction of propagation. However, only recently it has been pointed out that b…
