Limits to wideband pulsed squeezing in a traveling-wave parametric amplifier with group-velocity dispersion.

چکیده
A theoretical method is developed to treat wideband pulsed squeezing in a traveling-wave parametric amplifier with group-velocity dispersion. Classical stochastic wave equations that are fully equivalent to operator equations of motion are developed and solved numerically. It is found that squeezing occurs over the entire phase-matching bandwidth, although the degree of squeezing decreases when the pump-pulse duration is shorter than the inverse of this bandwidth.

Quantum wideband traveling-wave analysis of a degenerate parametric amplifier
We develop a wideband traveling-wave formalism for analyzing quantum mechanically a degenerate parametric amplifier. The formalism is based on spatial differential equations-spatial Langevin equations-that propagate temporal Fourier components of the field operators through the nonlinear medium. In addition to the parametric nonlinearity, the Langevin equations include absorption and associated...
متن کاملDecomposing a pulsed optical parametric amplifier into independent squeezers
Abstract We discuss the concept of characteristic squeezing modes applied to a travelling-wave optical parametric amplifier pumped by an ultrashort pulse. The characteristic modes undergo decoupled single-mode squeezing transformations, and therefore they form a useful basis to describe the evolution of the entire multimode system. This provides an elegant and intuitive picture of quantum stati...
متن کاملLight as a quantum fluid : a new quantization technique of optical fields based on X-waves and its application to entanglement in parametric amplification
In the framework of the paraxial and of the slowly varying envelope approximations, with reference to a normally dispersive medium or to vacuum, I report a new approach to field quantization. The electromagnetic field is given as a continuous superposition of non-dispersive and non-diffracting wave-packets (namely X-waves). This enables a new representation of a pulsed beam as a quantum fluid. ...

متن کاملSqueezing in a quasi-phase-matched LiNbO(3) waveguide.
We report traveling-wave quadrature squeezing at 1064 nm in a quasi-phase-matched LiNbO(3) waveguide, avoiding the gain-induced diffraction encountered in bulk squeezing experiments. The 10-mm-long singlemode waveguide parametric amplifier exhibited a gain of 1.9, averaged over the 20-ps mode-locked pulses, with only 0.5 W of peak pump power at 532 nm. Independent waveguides were employed for t...
