Reduction of phase-induced intensity noise in a fiber-based coherent Doppler lidar using polarization control.
Optimization of signal-to-noise ratio is an important aspect in the design of optical heterodyne detection systems such as a coherent Doppler lidar (CDL). In a CDL, optimal performance is achieved when the noise in the detector signal is dominated by local oscillator shot-noise. Most modern CDL systems are built using rugged and cost-efficient fiber optic components. Unfortunately, leakage sign...
متن کاملIntensity noise of mode-locked fiber lasers.
Intensity noise of mode-locked fiber lasers is characterized systematically for all major mode-locking regimes over a wide range of parameters. We find that equally low-noise performance can be obtained in all regimes. Losses in the cavity influence noise strongly without a clear trace in the pulse characteristics. Given that high-energy fiber laser oscillators reported to date have utilized la...
متن کاملPolarization resolved intensity noise in vertical-cavity surface-emitting lasers
We report explicit analytical and numerical results for the polarization resolved intensity noise of verticalcavity surface-emitting lasers operating in the fundamental transverse mode. We describe the fluctuations of the linear and circular polarization components of linearly polarized states on both sides of a nonthermal polarization switching. Our description is valid for small and large bir...
متن کاملNonlinear Polarization Rotation for Fiber Lasers with UltraHigh Pulse Energy
This report introduces principles of fiber lasers passively mode-locked by nonlinear polarization rotation (NPR). Dispersion and nonlinearity management of the laser cavity play an essential role in determining the laser operation state. Different soliton operation of the laser is discussed. Taking advantage of weak soltion restriment of per-pulse energy of postive net cavity dispersion cavity,...
متن کاملNonlinear theory of polarization-mode dispersion for fiber solitons.
We consider the evolution of optical solitons inside a nonlinear dispersive fiber with random birefringence, causing polarization-mode dispersion. We convert the pair of coupled nonlinear Schrödinger equations satisfied by the orthogonally polarized components into a Fokker-Planck equation using the collective-variable approach. We solve this equation and derive expressions for the probability ...
