Noiseless phase quadrature amplification via electro-optic feed-forward
The transmission of small optical signals carried by coherent light is fraught with difficulty. Attenuation of the optical power causes degradation of the signal-to-noise ratio as the signal recedes into the quantum noise of the beam. A simple method to rectify this problem would be to amplify the signal. However this is not a trivial exercise as phase insensitive amplifiers, such as laser ampl...
متن کاملProtection from Feed-Forward Amplification in an Amplified RNAi Mechanism
The effectiveness of RNA interference (RNAi) in many organisms is potentiated through the signal-amplifying activity of a targeted RNA-directed RNA polymerase (RdRP) system that can convert a small population of exogenously-encountered dsRNA fragments into an abundant internal pool of small interfering RNA (siRNA). As for any biological amplification system, we expect an underlying architecture...
متن کاملPyro-electro-optic phase gratings.
A new physical mechanism is proposed for generating transient phase gratings in transparent pyroelectric materials. The mechanism combines the pyroelectric and electro-optic effects to convert spatial intensity variations into transient phase gratings. The grating diffraction efficiency increases with a figure of merit that is proportional to the pyroelectric, electro-optic, and absorption coef...
متن کاملFeed-forward/Feed-backward Mechanical Amplification in the Mouse Cochlea
Introduction Sound vibrations are collected from the external environment by the eardrum and are guided to the basilar membrane in the cochlea. Pressure differences in the two scalae of the cochlea result in a traveling wave on the basilar membrane (figure 1). The tiny displacements are detected by the deflection of thousands of hair cells, situated along this membrane. It is hypothesized that ...
متن کاملNoiseless Optical Amplification of Images
We used a spatially broadband optical parametric amplifier for image amplification. In the phasesensitive configuration of the amplifier, we observed noiseless amplification of input images. For a gain of 2.5, we measured noise-figure values of (0.2 6 0.6) and (0.4 6 0.5) dB, respectively, for two amplifiers of different lengths. These experimental values agree with theory (for an ideal noisele...
