Title: Levitated optomechanics with a fiber Fabry-Perot interferometer,
Abstract: In recent years quantum phenomena have been experimentally demonstrated on
variety of optomechanical systems ranging from micro-oscillators to photonic
crystals. Since single photon couplings are quite small, most experimental
approaches rely on the realization of high finesse Fabry-Perot cavities in
order to enhance the effective coupling. Here we show that by exploiting a,
long path, low finesse fiber Fabry-Perot interferometer ground state cooling
can be achieved. We model a 100 m long cavity with a finesse of 10 and analyze
the impact of additional noise sources arising from the fiber. As a mechanical
oscillator we consider a levitated microdisk but the same approach could be
applied to other optomechanical systems.
