报告题目： Ge-based Photodetectors, Advanced Nano-electronic Devices, and Their Integration Platform to Enable Future Opto-Eletronic Integrated Circuits
The first part of this talk will focus on the recent progress of various Germanium-Tn (GeSn)-based photodetectors for 2 μm wavelength band which has emerged as a promising candidate for next communication window, extending operation wavelengths of current communication systems from near infrared range (NIR) of around 1.31 or 1.55 μm to short-wave infrared range (SWIR). In order to explore the full potential of photodetectors, heterogeneous integration of them with advanced nano-electronic devices to realize optoelectronic integrated circuits (OEICs) is highly desired. Therefore, in the second part of the talk, I will have a brief review on the recent development of advanced nano-electronic devices and approaches of 3D heterogeneous integration of electronic components with different functionalities. To leverage on such integration to realize chip-based systems for quantum application would also be discussed.
