We numerically analyze phase-sensitive parametric amplification of a multi-pixel text image and demonstrate that ~10-dB gain is achievable with ~10-kW total pump peak power, which makes it compatible with compact pump sources.
We demonstrate a near-noiseless amplification scheme for analog optical signals. The noise figure of a frequency-non-degenerate phase-sensitive fiber parametric amplifier is measured to be close to the Raman limit (~sime 0.5 dB) in the fiber.
We demonstrate an ultra-low-noise fiber-optic phase-sensitive amplification scheme that is capable of providing more than 10 dB of gain on a 40 MHz analog signal.
Employing all-optical means to prepare phase-coherent input signal-idler pairs, we implement a multichannel in-line phase-sensitive fiber-parametric amplifier. Feasibility of three-channel operation using a single pump is demonstrated.
The non-zero response time of the Kerr nonlinearity sets a fundamental limit on the noise figure of phase-insensitive fiber parametric amplifiers and wavelength converters. Our theory shows good agreement with experiments.
Parametric amplifiers can boost signals with 0 dB noise-figure penalty, which for conventional linear optical amplifiers approaches 3 dB at high gains. We will present results on noise performance of fiber optical parametric amplifiers, focusing on regimes of noiseless signal amplification.
