Sources of excess noise in photonic links and components that originate in the optical domain and manifest as low-frequency noise in the radio-frequency RF domain were studied double Rayleigh scattering-induced relative intensity noise and component-induced phase noise. Techniques to reduce excess noise, such as optimization of link architecture, component biases, and DC photocurrent levels were applied. Fiber-based optoelectronic oscillators were built and characterized, one of which incorporated a method to potentially minimize close-in RF phase noise that entailed using the phase noise impressed on one continuous-wave laser wavelength to cancel that impressed on another.
