Three-wave mixing with three incoming waves: signal-idler coherent attenuation and gain enhancement in a parametric amplifier.
نویسندگان
چکیده
We demonstrate the time-reversed process of nondegenerate three-wave parametric amplification from three distinct sources in the fully nonlinear regime using a Josephson amplifier. In the reverse process, coherent attenuation, signal and idler beams destructively interfere in the presence of a pump to generate additional pump photons. This effect is observed through the symmetric phase-dependent amplification and attenuation of the signal and idler beams and, in the depleted pump regime, through the phase-dependent modulation of the amplifier gain, directly probing the enhancement of the pump. Results are found to be in good agreement with theory.

Phase-coherent all-optical frequency division by three
The properties of all-optical phase-coherent frequency division by 3, based on a self-phase-locked continuous-wave ~cw! optical parametric oscillator ~OPO!, are investigated theoretically and experimentally. The frequency to be divided is provided by a diode laser master-oscillator power-amplifier system operated at a wavelength of 812 nm and used as the pump source of the OPO. Optical self-pha...

We describe the progress in fiber-based phase-sensitive parametric amplifiers in both frequency-degenerate and frequency-nondegenerate configurations. We discuss their applications for phase regeneration, as well as for lumped and distributed noiseless amplification. 2005 Optical Society of America OCIS codes: (060.2320) Fiber optics amplifiers and oscillators; (190.4410) Nonlinear optics, par...
متن کاملNegative-resistance models for parametrically flux-pumped superconducting quantum interference devices
A Superconducting QUantum Interference Device (SQUID) modulated by a fast oscillating magnetic flux can be used as a parametric amplifier, providing gain with very little added noise. Here, we develop linearized models to describe the parametrically flux-pumped SQUID in terms of an impedance. An unpumped SQUID acts as an inductance, the Josephson inductance, whereas a flux-pumped SQUID develops...
متن کاملDegenerate four waves mixing in multilayer nanoshell
We will present a detailed investigation of intersubband transitions process in core-multi shells quantum dots. The confined wave functions and eigenenergies of electrons in quantum dots have been calculated under the effective-mass approximation by solving a three-dimensional Schrodinger equation. Excellent dependence is found between size effects, time relaxation and degenerate four wave mixi...
