Individual Nanostructures in an Epsilon-Near-Zero Material Probed with 3D-Sculpted Light
Brian Kantor, Lisa Ackermann, Victor Deinhart +3
Epsilon-near-zero (ENZ) materials, i.e., materials with a vanishing real part of the permittivity, have become an increasingly desirable platform for exploring linear and nonlinear…
Photonic integrated processor for structured light detection and distinction
Johannes Bütow, Varun Sharma, Dorian Brandmüller +2
Integrated photonic devices have become pivotal elements across most research fields that involve light-based applications. A particularly versatile category of this technology are…
Protecting quantum modes in optical fibres
M. A. T. Butt, P. Roth, G. K. L. Wong +7
Polarization-preserving fibers maintain the two polarization states of an orthogonal basis. Quantum communication, however, requires sending at least two nonorthogonal states and t…
Generating free-space structured light with programmable integrated photonics
Johannes Bütow, Jörg S. Eismann, Varun Sharma +2
Structured light is a key component of many modern applications, ranging from superresolution microscopy to imaging, sensing, and quantum information processing. As the utilization…
