Paper Abstract

A Sagnac Interferometer has been built with a one hundred meters monomode fiber propagating a 0.6328 µm wavelength laser light. An exploitable measurement corresponds to a rotation rate of 8.10-3 radian per second. The noise corresponds to 1,6.10-3 radian per second. This noise is about 60 dB above quantum noise. The sources of fluctuations must be analysed and reduced. One cif them is the mechanical instability which can be improved by building the interferometer with integrated optics.
