以溶液处理的纳米晶形式制备的Percent材料和用于自顶向下的制造技术对于开发低成本和高质量的集成光电子电路非常有吸引力。特别地，高度期望可以连接到芯片上的光导结构的集成小型化相干光源。为了以低损耗光学模式控制在小覆盖区上传播的光，采用长程表面等离子体激元（LRSPP）波导。在这里，我们展示了一个片上制造的光子等离子体激元的混合系统组成的钙钛矿激光结构耦合到LRSPP波导实现低激光阈值和超过100 μ m的传播长度。通过设计没有任何蚀刻步骤的制造技术，使得在制造期间防止钙钛矿材料劣化和激光腔的表面粗糙度的形成成为可能。
Perovskite materials prepared in the form of solution-processed nanocrystals and used in top-down fabrication techniques are very attractive to develop low-cost and high-quality integrated optoelectronic circuits. Particularly, integrated miniaturized coherent light sources that can be connected to light-guiding structures on a chip are highly desired. To control light propagating on a small footprint with low-loss optical modes, long-range surface plasmon polariton (LRSPP) waveguides are employed. Herein, we demonstrate an on-chip fabricated photonic-plasmonic hybrid system consisting of a perovskite lasing structure coupled to an LRSPP waveguide achieving a low lasing threshold and a propagation length over 100 mu m. Preventing perovskite material degradation and the formation of surface roughness of the laser cavity during fabrication is made possible by designing a fabrication technique without any etching step.
