Squeezed light generation is demonstrated using a new scheme of nonlinear fiber loop mirror. The squeezed light can be generated stably in a compact setup and the phase difference can be changed arbitrarily. Using a 100 ps mode-locked pulse laser at 1.064 µm and 0.85 µm single-mode fiber, the quantum noise reduction of 2.0 dB below the shot noise level is observed in the frequency range of 25–35 MHz. Accounting for the detection efficiency, this corresponds to 2.9 dB squeezing.

Purification of Squeezed Vacuum Pulse Generated from a Sagnac Loop Fiber Using Linear Optics and Conditional Homodyne Detection

Kenichi Hirosawa, Yoshinori Momose, Hidetake Ushio +2 more

Purification of quadrature squeezed vacuum pulses at the wavelength of 1.5 µm generated from a Sagnac loop fiber interferometer is experimentally demonstrated using linear optics and conditional homodyne detection. The anti-squeezed quadrature variance degraded by guided acoustic wave Brillouin scattering in the fiber is significantly improved from 12.6 to 4 dB after the post selection, while the squeezed quadrature variance of -0.7 dB slightly decreases to -0.3 dB due to the linear optical loss caused by a beam splitter. This result agrees well with the theory.
