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.
