| Outline of Research at the Start |
We employ our developed pump-phase-noise-free optical multicast technique to generate multiple low phase-noise light sources optimized for long-range and parallel coherent LiDAR applications. Furthermore, through strategic pump configuration within a multicast setup via inverse system design, we achieve intelligent scalability, facilitating tailored scaling of the light sources.
|
| Outline of Annual Research Achievements |
We have published 7 international journal papers and 6 international conference papers. Notably, our work in APL Photonics has garnered recognition as exemplary research in optoelectronics, selected for "High-Quality Research in Optoelectronics" by the journal. In this pursuit, we've successfully designed and fabricated an ultrafast electro-optic modulator via the heterogeneous integration of silicon and thin-film lithium niobate. Additionally, we've developed an algorithm for controlling pump wavelengths, aimed at intelligently scaling multiple laser sources for LiDAR systems.

| Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The project is proceeding smoothly under our management. We have successfully developed the algorithm essential for our proposed system. Additionally, we've acquired the necessary instruments and components to facilitate our experimental demonstrations.
|
| Strategy for Future Research Activity |
In the upcoming year, our focus will be on designing a silicon nitride-based microring resonator to generate the optical comb source crucial for our proposed LiDAR system. Furthermore, we plan to design and fabricate high-speed silicon polymer hybrid EO modulators to enable chirp modulation in the LiDAR systems.
