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.

该项目提案的主要目标是研究超低相位噪声光电锁相环的概念，其输出频率应连续可调超过一个八度，并使用基于二极管的飞秒脉冲激光器作为基准振荡器。进一步的目标是研究光通信中使用现成元件的光电鉴相器原理，并利用硅光子学技术通过这些鉴相器概念实现光电频率合成器，从而实现超紧凑的尺寸和低成本。此外，将首次建立基于飞秒脉冲激光器的光电整数N和分数N锁相环的数学模型，以预测动态和静态控制行为、相位噪声、稳定性和杂散频率的产生。
