Application of Femtosecond Light Sources to Generation of Low Noise Microwave Signals

该研究项目的主要目标是开发能够在光学和微波频率上产生光谱纯信号的光子振荡器的原型。该项目还旨在了解影响基于蓝宝石加载腔谐振器的经典微波振荡器频率稳定性的噪声机制。通过对这种谐振器进行低温冷却，我们计划创造一种新的极低噪声和经济可行的微波信号源。拟议中的研究将丰富振荡器频率控制领域，产生精确噪声测量的新技术，并加强澳大利亚在微波和光子科学方面的前沿地位。

The main goal of the research project is to develop prototypes of photonic oscillators capable of generating spectrally pure signals both at optical and microwave frequencies. The project is also aimed at understanding noise mechanisms affecting frequency stability of classical microwave oscillators based on sapphire loaded cavity resonators. By cryogenically cooling such resonators we plan to create a new family of extremely low noise and economically viable microwave signal sources. The research proposed will enrich the field of oscillator frequency control, give rise to new techniques for precision noise measurements and reinforce Australia's position at the forefront of microwave and photonic science.
