Engineering Scalable Quantum Light Sources for Telecom Applications
Recently, Innolume hosted a seminar dedicated to the latest research in quantum light sources for telecommunication applications. The speaker of the event was Dr. Elizaveta Semenova, who presented the results of her work in this field.
Dr. Semenova is working at DTU in Copenhagen. Her research activities include quantum dots (QDs) epitaxial growth and nanofabrication.
Key Topics of the Presentation
- Dr. Semenova emphasized that the scalability of quantum communications is achievable through integrated photonics. The use of QDs as quantum light sources operating in the telecom C-band, enables the creation of effective solutions for global secure communication and distributed quantum computing based on the existing telecom infrastructure.
- During the seminar Dr. Semenova presented various epitaxial methods to grow InAs/InP quantum dots operating in the telecom C-band and their characteristics investigated via quantum optical spectroscopy methods.
- One of the key topics of the seminar was development of deterministic fabrication process of quantum photonic devices based on single QDs operating in the telecom C-band with yield above 30%.
We thank Dr. Elizaveta Semenova for her interesting and insightful presentation and continue to follow trends and developments in the field.
