Major goals of the project proposal are the investigation of concepts for ultra-low-phase-noise optoelectronic phase-locked loops of which the output frequency shall be contionously tunable over more than an octave and which uses diode-based femtosecond pulse lasers as reference oscillators. Further goals are the investigation of optoelectronic phase detector principles using off-the-shelf components for optical communications and to realize the optoelectronic frequency synthesizer by means of these phase detector concepts using silicon photonics technology thus achieving ultra-compact size and low cost. In addition, for the first time a mathematical model of optoelectronic integer-N and fractional-N phase-locked loops based on femtosecond pulse lasers shall be developed allowing to predict dynamic and static control behaviour, phase noise, stability, and spurious frequency generation.
