Distinguished Lecture: Silicon Photonics from Device Innovation to System Integration by Prof Linjie Zhou

Photonics Society

Silicon photonics has been regarded as one of the enabling technologies that can integrate multiple passive and active photonic components on a single compact chip.

The CMOS compatibility of silicon photonics offers a low-cost solution for high-volume massive production, pushing forward the rapid development of optical chips and modules for telecom and datacom applications. In this talk, I will present our recent progress in silicon photonics research from device design, fabrication, characterization to large-scale photonic chip integration. In particular, we have investigated nonvolatile silicon-Ge2Sb2Te5(GST) hybrid photonic devices for optical switching and memory. Upon phase change of GST from the amorphous state to the crystalline state, the complex refractive index changes dramatically, leading to reduced device size and power consumption.

In the photonic integration front, we have demonstrated optical switch matrix, optical true-time delay line and microwave filter chips that can be reconfigured to achieve different performance to satisfy a variety of applications.
