Thesis title: On-chip signal processing based on linear optics and nonlinear stimulated Brillouin scattering

Supervisors: Benjamin EGGLETON

Thesis abstract:

On-chip signal processing is a key technology that provides a compact form factor, low energy costs and a large bandwidth bandwidth. These advantages underpin the next- generation wireless communications technologies and applications in electronic-warfare for defence and security applications. Using integrated photonic devices and novel nonlinear optical process has been considered as a promising solution, due to their distinct and tailarable optical properties. This study mainly focuses on the signal processing and manipulations based on the integrated optical ring resonator and stimulated Brillouin process (SBS).

The integrated optical ring resonators on passive material platforms, as fundamental building blocks in micro/nano photonics, show unique phase responses that enable the implementations of different functionality, such as high-resolution signal filtering with negligible losses, and radio-frequency signal time delay.

On the other hand, chalcogenide glass as an active material platform, opens a new way to achieving signal amplification, optical and microwave source, and nonreciprocal devices, which are hardly realized by using passive material platforms. The study of SBS in integrated photonic circuits can be exploited to foster the developments of compact and highly efficient chip-scale devices, such as nanolasers, microwave sources and isolators on CMOS compatible platforms.

Through combining these advantages from the passive and active processes, a hybrid platform shows a great potential of integrating comprehensive funcationalities for signal generation and processing on a same chip, which will be a revolutionary technology for future applications.
