Coupling of a nanofiber to an intracavity optical lattice — •Bernd Welker, Thorsten Österle und Sebastian slama — Center for Quantum Science and Physikalisches Institut, Universität Tübingen

Recently, nanofiber-induced losses inside optical cavities have been analyzed [1]. The subwavelength dimension of the nanofiber leads to a considerably small loss rate, described by Mie scattering at a dielectric cylinder. This makes these nanofibers potentially useful as substrates for achieving strong coupling of nanoparticles with optical cavity modes. Here, we show how the loss rate and scattering of light from the cavity mode into the guided mode of the fiber depends on the fiber position along the intracavity optical lattice. We observe a strong dependence on the fiber diameter and the polarization of light.
