Abstract

With a short fiber interferometer, guided-acoustic-wave Brillouin scattering (GAWBS) is suppressed in two ways: less phase noise is accumulated, and the round-trip time through the fiber can be made shorter than the GAWBS inverse bandwidth. This paper presents some experimental results of squeezing with a short fiber by using two different schemes. The first is a self-phase stabilized ring squeezer, proposed by Shirasaki el al.¹ The second is a new linear scheme that has better mode overlap of the local oscillator and squeezed radiation than does the ring squeezer.
