A folded-sandwich polarization-entangled two-color photon pair source with large tuning capability for applications in hybrid quantum architectures
Otto Dietz, Chris Müller, Thomas Kreißl +4
We demonstrate a two-color entangled pho ton pair source which can be adapted easily to a wide range of wavelengths combinations. A Fresnel rhomb as a geometrical quarter-wave plat…
Coupled mode approach to square gradient Bragg reflection resonances in corrugated dielectric waveguides
Otto Dietz, Günter Kewes, Oliver Neitzke +1
We demonstrate the appearance of unexpected reflection resonances in corrugated dielectric waveguides. These are due to the curvature of the boundary. The effect is as strong as th…
Reflection resonances in surface-disordered waveguides: strong higher-order effects of the disorder
J. Doppler, J. A. Méndez-Bermúdez, J. Feist +5
We study coherent wave scattering through waveguides with a step-like surface disorder and find distinct enhancements in the reflection coefficients at well-defined resonance value…
Surface scattering and band gaps in rough waveguides and nanowires
O. Dietz, H. -J. Stöckmann, U. Kuhl +5
The boundaries of waveguides and nanowires have drastic influence on their coherent scattering properties. Designing the boundary profile is thus a promising approach for transmiss…
Transmission in waveguides with compositional and structural disorder: experimental effects of disorder cross-correlations
O. Dietz, U. Kuhl, J. C. Hernández-Herrejón +1
We analyse the single-mode transmission of microwaves in a guide with internal random structure. The waveguide contains scatterers characterised by random heights and positions, co…
Microwave realization of quasi one-dimensional systems with correlated disorder
O. Dietz, U. Kuhl, H. -J. Stoeckmann +2
A microwave setup for mode-resolved transport measurement in quasi-one-dimensional (quasi-1D) structures is presented. We will demonstrate a technique for direct measurement of the…
