Integrated Visible to SWIR Lasers and Photonics for Cold Atom and Trapped-Ion Quantum Sciences

Event Details

Advances in atomic and quantum sciences have enabled new fundamental measurements, communications and computation that existed only in theory just decades ago. Today, these experiments and their applications are undergoing transformations that require a scaling up in complexity, greatly improved reliability, and reduction in size, weight and cost. Yet the underlying lasers and optical infrastructure still occupies laboratory tables and racks, are power consuming and not reliable. Photonic integration has the potential to move the laser systems and other photonics on chip. In this talk we cover moving high performance quantum and atom visible to SWIR light infrastructure and precision optics to the chip-scale and early experiments with this technology, including ultra-narrow linewidth and frequency stabilized lasers, reference cavities, ultra-low loss waveguides, and other optics to deliver precision laser light to atomic transitions and perform quantum experiments including strontium neutral and trapped ion and neutral rubidium species. Future prospects will be described for quantum sensing, computation, and communication.
