Abstract

We show that whispering gallery modes on the surface of optical fibers can be reflected from the optical fiber facet. Due to reflection, a locking effect occurs near the optical fiber facet for the whispering gallery modes with an axial component of the wave vector. We obtained an analytical expression for determining the resonant wavelengths. We also experimentally measured the phase velocity of the optical pulse propagating in whispering gallery modes and reflecting from the fiber facet.
