研究目的
To review the recent progress in waveguide-integrated graphene photonic devices and their applications in sensing and communication.
研究成果
Waveguide-integrated graphene photonic devices offer significant advantages for sensing and communication applications, including enhanced light-matter interaction and compatibility with CMOS technology. Future research should focus on improving sensor sensitivity and specificity, optimizing modulator and photodetector designs, and advancing fabrication processes for large-scale integration.
研究不足
The development of waveguide-integrated graphene photonic sensors is still in its infancy, with most research focused on fiber and SPR sensors rather than PICs. The effects of doping and defects of graphene need further investigation to improve sensitivity and specificity. For modulators and photodetectors, designs with enhanced light-matter interaction and improved carrier transport are needed. The fabrication process requires improvement to meet wafer process line criteria, with a need for CMOS-compatible metal contact fabrication for large-scale chip manufacturing.
