Abstract
Microwave signals of extreme spectral purity are of great interest in a large variety of applications ranging from deep-space navigation systems to synchronization of large scale facilities as well as pulse-Doppler radars and precision spectroscopy. Photonic microwave generation schemes, in which a mode-locked laser is synchronized to an ultra-stable laser reference, allow unparalleled levels of phase noise through photodetection of the low-jitter optical train of pulses [1]. However, the photodetection process is known to introduce excess phase noise by transferring the baseband amplitude noise of the mode-locked laser to the phase noise of the output radio-frequency carrier [2,3], hereby spoiling the quality of the phase transfer. Although this conversion is easily observed, complete understanding of its process and its relation with other parameters remains unattended.
