Critical quantum fluctuations in the degenerate parametric oscillator
We develop a systematic theory of critical quantum fluctuations in the driven parametric oscillator. Our analytic results agree well with stochastic numerical simulations. We also compare the results obtained in the positive-P representation, as a fully quantum-mechanical calculation, with the truncated Wigner phase-space equation, also known as the semiclassical theory. We show when these resu...

متن کاملLimits to squeezing in the degenerate optical parametric oscillator
We develop a systematic theory of quantum fluctuations in the driven optical parametric oscillator, including the region near threshold. This allows us to treat the limits imposed by nonlinearities to quantum squeezing and noise reduction in this nonequilibrium quantum phase transition. In particular, we compute the squeezing spectrum near threshold and calculate the optimum value. We find that...
متن کاملCritical fluctuations and the rates of interstate switching near the excitation threshold of a quantum parametric oscillator.
We study the dynamics of a nonlinear oscillator near the critical point where period-two vibrations are first excited with the increasing amplitude of parametric driving. Above the threshold, quantum fluctuations induce transitions between the period-two states over the quasienergy barrier. We find the effective quantum activation energies for such transitions and their scaling with the differe...
متن کاملFrequency Locking in a Degenerate Polarization Mixing Optical Parametric Oscillator
A polarization mixing OPO was demonstrated, that emits a single, linearly polarized narrow linewidth beam, fixed at degeneracy, independent of crystal temperature. The frequency locking is explained in terms of balanced roundtrip phase-matching condition. ©2005 Optical Society of America OCIS codes: (190.2620) Frequency conversion; (190.4410) Nonlinear optics, parametric processes; (190.4970) P...
