Passive and Thermo-Optic Characterization of Long-Range Surface Plasmon-Polariton Structures in CYTOP
… cutback curves were drawn and S-bends, Y-junctions, Mach-Zehnder interferometers, and couplers were tested. Results show that the fabricated waveguide thicknesses are inconsistent and thinner than designed, and improvement of their fabrication quality is necessary. In thermo-optic …

QUANTUM TRANSPORT WITH COLD ATOMS
… is absent for bosonic atoms. Within atomic Y-junctions, we find negative reflections that resemble Andreev-reflections known from metal-superconductor interfaces. Further, we show that topological pumping within atomic ring systems can be used to create highly entangled NOON states. Finally, …

Broadband electrooptic modulators based on gallium arsenide materials
… employing both multimode interferometers and Y-junctions as power splitters. A self-aligned fabrication mask set and process are developed and demonstrated, verifying the performance of the modulator epitaxial heterostructures through the demonstration of waveguiding and optical power splitting. …

A combined experimental and theoretical approach towards the understanding of transport in one-dimensional molecular nanostructures
This thesis comprises detailed experimental and theoretical investigations of the transport properties of one-dimensional nanostructures. Most of the work is dedicated to the exploration of the fascinating effects occurring in single wall carbon nanotubes (SWCNT). These particular nanostructures …
