Nonlinear fiber system for shot-noise limited intensity noise suppression and amplification
Nonlinear fiber system for shot-noise limited intensity noise suppression and amplification
We propose a nonlinear fiber system for shot-noise limited, all-optical intensity-noise reduction and signal amplification. The mechanism is based on the accumulation of different nonlinear phase shifts between orthogonal polarization modes in a polarization-maintaining fiber amplifier in combination with an implemented sinusoidal transmission-function. The resulting correlation between the input intensity-fluctuations …
