Fiber Fabry--Perot (FFP) resonators of a few centimeters are optimized as a function of the reflectivity of the mirrors and the dimensions of the intra-cavity waveguide. Loaded quality factor in excess of 109, with an optimum of 4__x__109, together with an intrinsic quality factor larger than 1010 and intrinsic finesse in the range of 105 have been measured. An application to the stabilization of laser frequency fluctuations is presented.
