ABSTRACT:  High Q optical microcavities based on Whispering Gallery
Modes (WGM) enable a number of applications as narrowband filtering,
nonlinear optics, microlasers, and sensing. Microspheres and
microcylinders made of Er/Yb doped optical fiber enable all-optical,
pump-assisted, thermal tuning of high-Q WGM resonances. WGM resonances
of an optical fiber itself define a unique tool for the characterization
of fiber material and fiber components. Accurate characterization of
thermal effects is possible, such as pump-induced temperature increase
in doped optical fibers and thermal effects induced by an optical signal
of moderate power along fiber gratings. WGM resonances permit a full
characterization of the elasto-optic effect in optical fibers under
axial strain, enabling a direct measurement of the anisotropy and the
determination of the individual Pockels' coefficients.
