Optical diode based on the chirality of guided photons
C. Sayrin, C. Junge, R. Mitsch +5
Photons are nonchiral particles: their handedness can be both left and right. However, when light is transversely confined, it can locally exhibit a transverse spin whose orientati…
Nonlinear pi phase shift for single fiber-guided photons interacting with a single atom
Jürgen Volz, Michael Scheucher, Christian Junge +1
Realizing a strong interaction between individual optical photons is an important objective of research in quantum science and technology. Since photons do not interact directly, t…
Fiber-optical switch controlled by a single atom
Danny O'Shea, Christian Junge, Jürgen Volz +1
We demonstrate highly efficient switching of optical signals between two optical fibers controlled by a single atom. The key element of our experiment is a whispering-gallery mode…
Strong coupling between single atoms and non-transversal photons
Christian Junge, Danny O'Shea, Jürgen Volz +1
We investigate the interaction between single quantum emitters and non-transversally polarised photons for which the electric field vector amplitude has a significant component in…
Bottle microresonator with actively stabilized evanescent coupling
C. Junge, S. Nickel, D. O'Shea +1
The evanescent coupling of light between a whispering-gallery-mode bottle microresonator and a sub-wavelength-diameter coupling fiber is actively stabilized by means of a Pound-Dre…
Ultra-high Q whispering-gallery-mode bottle microresonators: properties and applications
D. O'Shea, C. Junge, S. Nickel +2
Highly prolate-shaped whispering-gallery-mode "bottle microresonators" have recently attracted considerable attention due to their advantageous properties. We experimentally show t…
