We are proud to share that our recent publication, “Lasing by Template‐Assisted Self‐Assembled Quantum Dots,” has been recognized as a Top-Viewed Article by Advanced Optical Materials for the year 2023!
This research addresses a key challenge in integrated photonics: the development of miniaturized, low-threshold laser sources. By leveraging a template-assisted self-assembly technique, we demonstrated distributed feedback (DFB) lasers using photostable core/shell quantum dots (QDs). Our approach enables precise subwavelength patterning via soft lithography and fine-tuned waveguide thickness through a Langmuir–Blodgett setup. The result is an impressively low lasing threshold of 0.6 mJ/cm² demonstrating the potential for scalable, efficient on-chip light sources.
Importantly, this recognition belongs not only to Kingslab but to a team effort. I would like to especially acknowledge my co-authors, Olha Aftenieva, Mohammad Adnan, and Swagato Sarkar, whose deep insights and dedicated contributions were essential to the success of this work.
We also deeply value the fruitful cooperation with Vladimir Lesnyak, Karl Leo, and Andreas Fery, whose expertise and collaboration greatly enriched this project.
We are excited by the ongoing impact of this work and look forward to advancing the field of quantum dot-based photonics even further.
