Cavity QED Based on Thermal Atoms Interacting with a Photonic Crystal Cavity: A Feasibility Study
Hadiseh Alaeian, Ralf Ritter, Muamera Basic +2
The paradigm of cavity QED is a two-level emitter interacting with a high quality factor single mode optical resonator. The hybridization of the emitter and photon wave functions m…
Coupling a thermal atomic vapor to an integrated ring resonator
Ralf Ritter, Nico Gruhler, Wolfram Pernice +3
Strongly interacting atom-cavity systems within a network with many nodes constitute a possible realization for a quantum internet which allows for quantum communication and comput…
Atomic vapor spectroscopy in integrated photonic structures
Ralf Ritter, Nico Gruhler, Wolfram Pernice +3
We investigate an integrated optical chip immersed in atomic vapor providing several waveguide geometries for spectroscopy applications. The narrow-band transmission through a sili…
Optical coherences and wavelength mismatch in ladder systems
A. Urvoy, C. Carr, R. Ritter +3
We investigate experimentally and theoretically the coherent and incoherent processes in open 3-level ladder systems in room temperature gases and identify in which regime electrom…
Cooperative non-equilibrium phase transition in a dilute Rydberg ensemble
Christopher Carr, Ralf Ritter, Christopher Wade +2
We demonstrate a non-equilibrium phase transition in a dilute thermal atomic gas. The phase transition, between states of low and high Rydberg occupancy, is induced by resonant dip…
Fabrication and characterization of an electrically contacted vapor cell
Renate Daschner, Ralf Ritter, Harald Kübler +4
We demonstrate the use of electrically contacted vapor cells to switch the transmission of a probe laser. The excitation scheme makes use of electromagnetically induced transparenc…
