Abstract

We demonstrate what is to our knowledge the first all-fiber squeezing experiment. A balanced Sagnac loop is used, and a record 6.1±0.2 dB of noise reduction below shot noise has been obtained without stabilization. A gigahertz Er-doped fiber laser and a high-power double-clad Er–Yb amplifier have been developed to suppress guided acoustic-wave Brillouin scattering and to make possible the all-fiber configuration.

Typical averaged spectrum at 8  MHz, 100-kHz resolution bandwidth piezo stack driven with a 5-Hz sinusoid. The squeezing is 6.1  dB, and the antisqueezing is 17  dB. The central dip does not go below shot noise because of insufficient voltage applied to the piezo stack.
