Researchers Demonstrate Efficient Integration of Quantum Dot Lasers on Silicon Chiplets

“The proposed integration technique can be applied to a variety of photonic integrated circuit designs, paving the way for a scalable, cost-effective monolithic integration of on-chip light sources for practical applications.”

Working with AIM Photonics and Analog Photonics, Researchers from the University of California, Santa Barbara (UCSB) have demonstrated a new method for integrating quantum dot lasers directly onto silicon photonics chiplets—a critical step toward scalable, cost-effective on-chip light sources.

This article describes how the team combined innovative growth and packaging techniques to address the material mismatch that has made it difficult to integrate III-V semiconductor lasers with silicon photonics.

The achievement, published in the IEEE Journal of Lightwave Technology, shows how collaborative research is advancing the performance and manufacturability of integrated photonic systems.
