Observation of -9 dB quadrature squeezing with improvement of phase stability in homodyne measurement.

We observe -9.01+/-0.14 dB of squeezing and +15.12+/-0.14 dB of antisqueezing with a local oscillator phase locked in homodyne measurement. Suzuki et al. have pointed out two main factors in [Appl. Phys. Lett. 89, 061116 (2006)], which degrade the observed squeezing level:phase fluctuation in homodyne measurement and intracavity losses of an optical… CONTINUE READING
