| Outline of Annual Research Achievements |
The research goes well this year. The main achievements include:
a) Since the scalability is an important aspect of the signal processing subsystem based on four-wave mixing, we conducted numerical simulations to explore an intelligently scalable multicast system based on four-wave mixing. This provides sufficient datasets for the next-stage research work.
b) The nonlinear device plays an important role in the subsystem. In addition to the previously used nonlinear fiber, we designed a silicon resonator with an optimized dispersion profile to provide efficient four-wave mixing effects in signal processing. The relevant results have been published in MDPI Photonics (SCI-indexed journal).

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
Our research work has progressed smoothly so far. Both numerical simulations and experimental investigations were well conducted. We have published our research results in peer-reviewed journals and conferences. The findings during the research also inspired us new ideas for other applications such as laser detection and ranging (Lidar).
|
| Strategy for Future Research Activity |
Based on the results we have obtained last year, we will develop an efficient pumping scheme to implement an intelligently scalable signal processing subsystem.
|
| Causes of Carryover |
Due to the influence of Coid-19, the delivery of some components was delayed.
