研究目的
To address four key scientific problems in silicon photonics: silicon electro-optic modulator design, advanced multiplexing mechanisms, polarization controlling, and fiber-to-chip coupling, with a focus on CMOS-compatibility for high-speed silicon-based optical interconnections.
研究成果
The dissertation successfully addresses key challenges in silicon photonics through CMOS-compatible device designs, demonstrating high-performance modulators, multiplexers, polarization controllers, and couplers. Future work includes optimizing electrode design, establishing high-speed test platforms, completing device testing, exploring packaging methods, and advancing towards large-scale optoelectronic integration and novel applications in sensing and communication.
研究不足
1. The design optimization of novel traveling-wave electrodes and signal integrity analysis are not fully explored. 2. Large-scale hybrid multiplexing and high-speed test platforms for Tb/s transmission are yet to be established. 3. Some polarization splitter-rotator device samples remain untested. 4. Low-cost industrial packaging methods for fiber-to-chip coupling need further exploration. 5. The research is at the verification stage of single components, with a long path to silicon-based optoelectronic integration.
