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，其输出频率应在一个倍频程以上连续可调，并使用基于二极管的飞秒脉冲激光器作为参考振荡器。进一步的目标是研究使用用于光通信的现成组件的光电相位检测器原理，并且通过使用硅光子技术的这些相位检测器概念来实现光电频率合成器，从而实现超紧凑尺寸和低成本。此外，还将首次开发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、稳定性和杂散频率生成。
