| Outline of Final Research Achievements |
Perovskites are highly promising for advanced photonic devices, such as small lasers, which play a crucial role in photonic integrated circuits. To date, existing perovskite lasers are typically grown as individual single crystals using methods like CVD or solution growth. However, these individual lasers cannot be precisely patterned or aligned on a substrate, limiting their practical applications.
In this project, we have successfully developed a novel self-healing lithographic patterning technique for realizing laser arrays based on perovskite quantum dots. This technique is compatible with standard semiconductor processes and offers significant advantages. It greatly improves the cavity quality of lithographic laser arrays, allowing for the fabrication of high-quality, large-area, high-crystallinity, and precisely size-controlled laser and photonic components using perovskites. Our work opens up new possibilities for the advancement of perovskite-based photonic devices.
