Quantum optical experiments towards atom-photon entanglement
Markus Weber
In 1935 EPR used the assumption of local realism to conclude in a Gedankenexperiment with two entangled particles that quantum mechanics is not complete. Based on this idea Bell co…
Measuring the temperature and heating rate of a single ion by imaging
Bharath Srivathsan, Martin Fischer, Lucas Alber +3
We present a technique based on high resolution imaging to measure the absolute temperature and the heating rate of a single ion trapped at the focus of a deep parabolic mirror. We…
Nonlinear optics with full three-dimensional illumination
Rojiar Penjweini, Markus Weber, Markus Sondermann +2
We investigate the nonlinear optical process of third-harmonic generation in the thus far unexplored regime of focusing the pump light from a full solid angle, where the nonlinear…
Design, Fabrication, and Characterization of Ta2O5 Photonic Strip Waveguides
Lars Liebermeister, Niko Heinrichs, Florian Böhm +6
Efficient coupling of single quantum emitters to guided optical modes of integrated optical devices is of high importance for applications in quantum information science as well as…
Shifting the phase of a coherent beam with a Yb ion: influence of the scattering cross section
Martin Fischer, Bharath Srivathsan, Lucas Alber +3
We discuss and measure the phase shift imposed onto a radially polarized light beam when focusing it onto an ion. In the derivation of the expected phase shif…
Fabrication and optical characterization of long-range surface-plasmon-polariton waveguides in the NIR
Markus Weber, Johannes Trapp, Florian Boehm +6
We experimentally demonstrate the propagation of long-range surface plasmon-polaritons in a nobel metal stripe waveguide at an optical wavelength of 780 nm. To minimize propagation…
