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…
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…
All-optical switching and strong coupling using tunable whispering-gallery-mode microresonators
D. O'Shea, C. Junge, M. Poellinger +2
We review our recent work on tunable, ultrahigh quality factor whispering-gallery-mode bottle microresonators and highlight their applications in nonlinear optics and in quantum op…
