Advanced VCSELs for Scalable Quantum Sensing Applications
Abstract
Vertical-Cavity Surface-Emitting Lasers (VCSELs) are pivotal to advancing quantum sensing technologies, offering compact, efficient, and scalable light sources for applications such as quantum atomic clocks, magnetometers, gyroscopes, and quantum imaging systems. Significant progress has been made in developing VCSELs with high optical power, precise spectral control, and robust polarization stability, demonstrating their suitability for driving atomic transitions and supporting quantum coherence.
Building upon these advancements, current efforts focus on transitioning VCSEL technologies from laboratory prototypes to manufacturable devices for large-scale quantum systems. This includes the design of scalable architectures optimized for manufacturability, such as wafer-level integration processes and monolithic fabrication techniques.
This presentation will explore:
- Key technological innovations in high efficiency VCSELs, emphasizing features critical for quantum sensing.
- Challenges and strategies in scaling these designs for high-volume industrial manufacturing while maintaining quantum-grade precision.
- A roadmap for integrating VCSELs into field-deployable quantum sensing systems, bridging laboratory development and commercial applications.
By addressing the unique requirements of quantum technologies and leveraging advancements in fabrication scalability, this work aims to establish VCSELs as a cornerstone for Quantum 2.0 applications, enabling compact, reliable, and cost-effective quantum sensing solutions.
