using a new numerical model, the pump-to-signal relative intensity noise (rin) transfer in singlepumpfiber optical parametric amplifiers for low modulation frequencies is investigated. the model includesfiber loss, pump depletion, as well as the gain saturation, and therefore, it can describe the practicalcircumstances associated with various applications of fiber optical parametric amplifiers....

High-gain optical parametric amplification is an important nonlinear process used both as a source of coherent infrared light and nonclassical light. In this work, we experimentally demonstrate approach to that enables extremely large gains with low energy requirements. conventional media driven by femtosecond pulses, multiple dispersion orders limit the effective interaction length available f...

In this paper the effect of parametric amplification in MEMS-based air-flow hairsensors is studied. With an AC-voltage controlled torsional stiffness the rotation of the hair can be influenced. With the appropriate amplitude, phase and frequency, the rotation of the torsional hair system is increased with respect to the case without parametric amplification. Therefore, parametric amplification ...
