This scheme allows the production of phase sidebands on the squeezed vacuum which facilitate phase locking in downstream applications.FrequenciesInterferometersLight amplifiersOptical beam splittersOptical resonatorsLow frequency squeezingParametric amplifiers Low-frequency squeezingOptical parametric amplifierPhase modulationSqueezed vacuum200210.1088/1464-4266/4/6/3092015-12-12
