Integrated Photonics Summer PhD Intern

HyperLight is at the forefront of the commercialization of thin-film lithium niobate (TFLN) integrated photonics - a material and process technology that is enabling high-performance scalable optical components across AI/datacom infrastructure hyperscale computing quantum computing sensing and beyond. Founded in 2018 and backed by leading venture capital weve built a team and a platform focused on real-world mass deployment of TFLN photonics technology.

At the core of our work is the TFLN Chiplet platform a modular integrated architecture designed for scalability manufacturability and seamless integration into complex systems. It offers a rare combination of extraordinary performance and industrial readiness enabling system developers across applications to deploy the technology fast and ready. We partner with our customers and suppliers from conceptualization design and prototyping phases all the way through mass production to ensure smooth and rapid deployment of TFLN photonic technology.

We believe our platform is the key in the golden age of integrated photonics to empower humanity to the next level. We assembled a world class team covering engineering business and operations. We believe in the power of integrity innovation collaboration and pragmatic solutions. Our diverse team thrives on challenges and is united by a shared commitment to excellence. We take pride in tackling complex challenges with curiosity humility and a deep sense of care for one another.

As HyperLight continues to expand we are looking for an Integrated Photonics Summer PhD Intern. This position offers a unique opportunity to participate in the technical parts of our integrated photonics product.
