Ultra-high-Q tunable whispering-gallery-mode microresonator
M. Pöllinger, D. O'Shea, F. Warken +1
Typical microresonators exhibit a large frequency spacing between resonances and a limited tunability. This impedes their use in a large class of applications which require a reson…

Ultra-sensitive surface absorption spectroscopy using sub-wavelength diameter optical fibers
F. Warken, E. Vetsch, D. Meschede +2
The guided modes of sub-wavelength diameter air-clad optical fibers exhibit a pronounced evanescent field. The absorption of particles on the fiber surface is therefore readily det…
