Kerr noise reduction and squeezing
We introduce a model of squeezing and noise reduction in the Kerr effect that accounts for noise in all quadratures of the driving field. Consequently we show that Kerr squeezing is much more sensitive to driving noise than squeezing produced by second harmonic generation (SHG). We experimentally demonstrate this sensitivity using a nonlinear system that tunes between strong classical SHG and K...
متن کاملNoise squeezing due to Kerr effect nonlinearities in optical fibres with negative dispersion
Kerr effect nonlinearities in optical fibres have been the subject of extensive studies [1 – 3]. Four wave-mixing (FWM) between the signal and the amplified spontaneous emission (ASE) noise was found to be an important source for system performance degradation, especially in systems using in-line optical amplifiers. With positive fibre dispersion, this effect is known as modulation instability ...
متن کاملSqueezing of Atomic Quantum Projection Noise
We provide a framework for understanding recent experiments on squeezing of a collective atomic pseudo-spin, induced by a homodyne measurement on off-resonant probe light interrogating the atoms. The detection of light decimates the atomic state distribution and we discuss the conditions under which the resulting reduced quantum fluctuations are metrologically relevant. In particular, we consid...
متن کاملNoise squeezing in a nanomechanical Duffing resonator.
We study mechanical amplification and noise squeezing in a nonlinear nanomechanical resonator driven by an intense pump near its dynamical bifurcation point, namely, the onset of Duffing bistability. Phase sensitive amplification is achieved by a homodyne detection scheme, where the displacement detector's output, which has a correlated spectrum around the pump frequency, is down-converted by m...
متن کاملStrong reduction of laser power noise by means of a Kerr nonlinear cavity
We demonstrated the power noise reduction of a continuous-wave laser field by means of an effective third-order Kerr nonlinear cavity. In contrast to conventional noise reduction schemes relying on linear cavities, a strong noise suppression at Fourier frequencies below the linewidth of the nonlinear cavity was possible. The laser light was reflected off a Kerr nonlinear cavity that had a half ...
