Photonic sources of pristine optical and microwave carriers

时间，相当于频率，是所有物理量中最精确测量的。几乎所有的物理学和工程学领域都依赖于时间和频率计量，因此依赖于基准振荡器。振荡器相位的随机波动限制了时间和频率测量的精度。提出了将光电振荡器作为纯微波载流子源的研究。主要的挑战是在组合中实现世界级的性能属性。我们的目标是一种可调的紧凑型OO，具有极低的噪声和高的长期稳定性，目标是在一个封装中实现硅光子集成。其战略是用大幅降低的噪音换取更紧凑的零部件。干涉仪和振荡器调谐的独创解决方案结合噪声抑制方法的新型振荡器结构的性能将通过理论建模、仿真验证和离散和集成原型的测试和测量来评估。激光噪声驱动了OEO中的许多噪声机制。巧合的是，激光器和光电振荡器都是同一类振荡器的例子，因此类似的降噪技术可能适用于光电振荡器和其他应用的激光器。人们强烈期望在不同的领域产生新的知识：组件噪声机制、噪声测量、噪声抑制方法、自动调谐控制、耦合振荡器动力学；以及光电和电光器件与硅光子学的混合。系统振荡器/时钟的噪声和长期稳定性在光学和无线通信、高速数字电子、雷达和激光雷达以及天文学等应用中具有重要意义。这种信号源的发展将对天气雷达产生重大影响，例如，必须探测到相对于载体具有很小多普勒频移的非常弱的回波。随着数字系统中使用的时钟频率不断增加，完全集成的OO将构成信通技术的突破。这项研究还将影响5G无线毫米波的产生和太赫兹辐射源的研究。该计划的结果将使加拿大受益，因为它将支持对以知识为基础的数字经济至关重要的信通技术的增长。它将通过具有市场影响的新产品和新工艺直接为财富创造做出贡献。它还将通过培训具有可转让技能的高素质人员来支持加拿大在信息和通信技术领域的领先地位，这是将知识从学术界转移到工业界的最有效手段。

Time, equivalently frequency, is the most precisely measured of all physical quantities. Almost all domains of physics and engineering rely on time and frequency metrology and hence on a reference oscillator. The random fluctuations of the phase of an oscillator limit the precision of time and frequency measurements. Research is proposed on optoelectronic oscillator (OEO) as a pure source of microwave carriers. The principal challenge is to achieve world-class performance attributes in combination. The goal is a tunable compact OEO with exceptionally low noise and high long-term stability targeting silicon photonic integration in one package. The strategy is to trade aggressively reduced noise for more compact components. The performance of novel oscillator architectures combined with noise suppression methods enable by an original solution to the tuning of interferometers and oscillators will be evaluated through theoretical modeling, verification by simulation and corroboration by test & measurement of discrete and integrated prototypes. Laser noise drives many of the noise mechanisms within an OEO. Serendipitously, both laser and OEO are examples of the same class of oscillator so similar noise reduction techniques to may be applied to lasers for OEO and other applications. There is a strong expectation of the generation of new knowledge in areas as diverse as: component noise mechanisms, noise measurement, noise suppression methods, automatic tuning control, coupled oscillator dynamics; and optoelectronic and electro-optic device hybridisation with silicon photonics. The noise and long-term stability of the system oscillator / clock is of major importance in applications such as optical & wireless communications, high speed digital electronics, radar & lidar, and astronomy. The development of such a source would have major impact, for example, on weather radar where very weak returns with small Doppler shifts relative to the carrier must be detected. With ever-increasing clock frequencies being used in digital systems, a fully integrated OEO would constitute a breakthrough in ICT. The research would also impact the generation of mm waves for 5G wireless and research into sources of THz radiation. The results of this program will benefit Canada by supporting the growth in ICT critical to a knowledge-based digital economy. It will contribute directly to wealth creation through new products and processes with a market impact. It will also support Canada's leading position in ICT by training of highly qualified personnel with transferable skills, which is the most effective means of knowledge transfer from academia to industry.
