2. Phase-sensitive amplifiers for nonlinearity impairment mitigation in optical fiber transmission links
Abstract : The fundamental limitations in fiber-optic communication are caused by optical amplifier noise and the nonlinear response of the optical fibers. The quantum-limited noise figure of erbium-doped fiber amplifiers (EDFAs) or any phase-insensitive amplifier is 3 dB. READ MORE

3. Nonlinear intrachannel distortion in high-speed optical transmission systems
Abstract : The Kerr nonlinearity in optical fibres tends to generate signal distortion in dispersion-managed fibre-optic communication systems. Within a wavelength channel, the resulting intrachannel effects are timing jitter, i.e. READ MORE

4. Noise and Saturation Properties of Fiber Optical
Abstract : Fiber Optical Parametric Amplifiers (FOPAs) are based on a highly efficient Four-wave Mixing process in highly nonlinearfibers and have gained a lot of interest since it was shown that ahigh gain can be obtained. They are multi-functional devices thatare not only limited to amplifying signals, but their wide range ofapplicability also include wavelength conversion, pulse-generation,optical sampling and also regeneration at very high bit-rates.

5. Nonlinearity mitigation in phase-sensitively amplified optical transmission links
Abstract : The fundamental limitations in fiber-optic communication are caused by optical amplifier noise and the nonlinear response of the optical fibers. The quantum-limited noise figure of erbium-doped fiber amplifier (EDFA) or any phase-insensitive amplifier is 3 dB. READ MORE
