摘要: A system and method for phase-readout/control and active stabilization on arbitrary interferometric phase in the optical interferometer platform is disclosed. The method makes use of a bi-colored polarization-multiplexed reference laser scheme. The disclosed scheme is based on two phase-locked reference signals with different frequencies that together remove the phase ambiguity. The two signals are polarization-multiplexed (either in free-space or optical fiber implementations) to enable easy separation and combining of these two signals through the use of polarization beam-splitters. The disclosed scheme provides a one-to-one map between phase and feedback signal levels, and enables phase-readout and stabilization even when one of the feedback-signals is at a maximum/minimum.

摘要: A system and a method for phase extraction of a multi-path interferometer, the method comprising generating a reference signal of a coherence length longer than an arm length difference of the multi-path interferometer; splitting the reference signal into a frequency shifted reference signal and an unshifted reference signal; recombining the frequency shifted reference signal and the unshifted reference signal into a polarization- and frequency-multiplexed reference signal, and feeding the polarization- and frequency-multiplexed reference signal to the multi-path interferometer; detecting frequency shifted and unshifted output signals of the multi-path interferometer; and determining the interferometer phase from the detected signal.

摘要: A method and a system method for generating optical multipartite quantum states, comprising generating optical fields by at least two different spontaneous four-wave mixing processes and overlapping the optical fields spontaneously generated from the different spontaneous four-wave mixing processes into a same resonator mode of a third-order nonlinear resonator. The system comprises a multi-colored laser source exiting a nonlinear third-order resonator at different resonance frequencies belonging to different mode families of the resonator.

摘要: A passive mode-locked laser method and system, the system comprising a nonlinear optical loop comprising a resonant nonlinear element, coupled to an amplification section by a beam splitter, the beam splitter splitting a light beam from the amplification section into light beams propagating in opposite directions around the nonlinear optical loop, the resonant nonlinear element acting as both a nonlinear element and a narrow bandwidth filter for the laser system, allowing mode-locking operation of the system on a single resonance of the resonant nonlinear element.
