Optical Squeezing with Self-Phase-Stabilized Scheme

Abstract

A nonlinear symmetric Mach-Zehnder interferometer was proposed for optical squeezing1,2, and it was shown that a nonlinear ring reflector with optical pulses is a practical realization of this squeezer2 (see Fig.1). Noise suppression in a balanced homodyne detection using this squeezing scheme was observed experimentally3,4.

Squeezing of pulses in a nonlinear interferometer

Masataka Shirasaki, H. A. Haus

A symmetric nonlinear Mach–Zehnder interferometer containing a Kerr medium performs the operation of squeezing. The operation is performed by the interference of cotraveling waves, and the pump wave is removed. This mechanism is broadband. We analyze the operation of the interferometer and determine the degree of shot-noise reduction achieved in a balanced detector. A modification of the interferometer into a fiber ring reflector is described that accomplishes the squeezing and the pump separation.

Soliton squeezing in asymmetric and symmetric fiber Mach-Zehnder nonlinear interferometers

Marco Fiorentino B, Jay E. Sharping, Paul L. Voss +3 more

Summary form only given. Several schemes to generate squeezed light by use of the Kerr nonlinearity in optical fibers have been devised. The most recent experiments used asymmetric Sagnac loops to produce amplitude squeezing. In our experiment the Sagnac geometry is "unfolded" into a Mach-Zehnder, wherein the two arms of the interferometer correspond to the polarization modes of a single-mode PM fiber. This setup allows us to switch from an asymmetric to a symmetric interferometer, and gives us full control of the phase and amplitude of the two interfering pulses. With these degrees of freedom, we are able to maximize noise reduction and perform a full measurement of the noise properties of the soliton squeezed pulses.

Squeezing performance of a nonlinear symmetric Mach–Zehnder interferometer using forward degenerate four-wave mixing

Masataka Shirasaki

A nonlinear symmetric Mach–Zehnder interferometer is analyzed. It performs squeezing and phase-sensitive amplification through forward degenerate four-wave mixing with automatic phase matching. Since the balanced interferometer is frequency insensitive, the operation is broadband. The squeezing performance is computed numerically by means of the quantum theory without approximation. This result is compared with the squeezing characteristics derived from the linearized representation. It is found that squeezed states can be produced without excess noise. Noise reduction of an interferometric measurement and phase-preserving amplification with this squeezer are also analyzed.

Soliton squeezing in a Mach-Zehnder fiber interferometer

Marco Fiorentino B, Jay E. Sharping, Prem Kumar +2 more

A scheme for generating amplitude squeezed light by means of soliton self-phase modulation is experimentally demonstrated. By injecting 180-fs pulses into an equivalent Mach-Zehnder fiber interferometer, a maximum noise reduction of $4.4\ifmmode\pm\else\textpm\fi{}0.3$ dB is obtained $(6.3\ifmmode\pm\else\textpm\fi{}0.6$ dB when corrected for losses). The dependence of noise reduction on the interferometer splitting ratio and fiber length is studied in detail.

Noise analysis of Mach-Zehnder squeezer for nonclassical input state

Masataka Shirasaki, Ilya Lyubomirsky, H. A. Haus

The squeezing by a nonlinear symmetric Mach–Zehnder interferometer is investigated when the input state of the pump is nonclassical. No linearization approximation is made. The analysis shows that the homodyne noise between the two outputs of the squeezer is suppressed well below the standard quantum limit if the uncertainty of the input photon number is not large. This fact suggests that, even if each output has large phase uncertainty, the two outputs are strongly phase correlated.

Enhanced fiber squeezing via local-oscillator pulse compression

Jeffrey H. Shapiro, Lance G. Joneckis

It is shown that the Gaussian-pulse-profile limit on fiber squeezing can be circumvented via LO pulse compression. In loop-mirror fiber-squeezing experiments the Mach-Zehnder interferometer (MZI) bright-fringe output pulse-augmented with an adjustable phase bias-is used as the LO pulse for homodyne detection of the MZI's dark-fringe output.>
